Right... so here's the kludge (sans checkinstall or vlpackager)
1) Download the sources.
2) Create a directory such as Unetbootin-319.
>mkdir Unetbootin-319
This is necessary because the source packager created a tar-bomb which unpacks into the current directory.
3) Move the source tarball into the directory you've created.
>mv unetbootin-source-319.tar.gz Unetbootin-319/
4) Change into the directory
>cd Unetbootin-319
5) Unpack the source:
>tar -xzvf unetbootin-source-319.tar.gz
6) Ensure that you have qt4 installed (use slapt-get if necessary)
7) Run the INSTALL script provided. This really just compiles the code:
>./INSTALL
You'll see a bunch of stuff like this:
Updating 'unetbootin_be.ts'...
Found 137 source text(s) (0 new and 137 already existing)
Updating 'unetbootin_de.ts'...
Found 137 source text(s) (0 new and 137 already existing)
Updating 'unetbootin_es.ts'...
Found 137 source text(s) (0 new and 137 already existing)
Updating 'unetbootin_fr.ts'...
Found 137 source text(s) (0 new and 137 already existing)
Updating 'unetbootin_he.ts'...
and then the usual make-noise:
/usr/lib/qt4/bin/uic unetbootin.ui -o ui_unetbootin.h
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DNOSTATIC -DNOSTATIC -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_NETWORK_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/lib/qt4/mkspecs/linux-g++ -I. -I/usr/lib/qt4/include/QtCore -I/usr/lib/qt4/include/QtCore -I/usr/lib/qt4/include/QtNetwork -I/usr/lib/qt4/include/QtNetwork -I/usr/lib/qt4/include/QtGui -I/usr/lib/qt4/include/QtGui -I/usr/lib/qt4/include -I. -I. -I. -o main.o main.cpp
...
It shouldn't take more than a couple of minutes to compile since everything seems to go into a single executable file: unetbootin
At this point you can run it as root. However, you are interested in creating a package.

Create a directory, call it anything you'd like. I choose "package".
>mkdir package
9) Now build up the directory structure you would like the executable to live in:
>mkdir package/usr
>mkdir package/usr/bin
10) Now copy unetbootin to the directory package/usr/bin
>cp unetbootin package/usr/bin/
11) Create an install directory (yes, we're doing this old-school)
>mkdir package/install
12) Using your favorite text editor, create a slack-desc file that looks something like this. Spacing and
number of lines matter. See
http://www.linuxpackages.net for a howto.
unetbootin: UNetbootin 319 Create bootable USB thumbdrive
unetbootin:
unetbootin: UNetbootin allows you to create bootable Live USB drives for a
unetbootin: variety of Linux distributions from Windows or Linux, without
unetbootin: requiring you to burn a CD. You can either let it download one
unetbootin: of the many distributions supported out-of-the-box for you, or
unetbootin: supply your own Linux .iso file if you have already downloaded
unetbootin: one or your preferred distribution is not on the list.

13) Copy this file into package/usr/install/ . Since I created it in my Unetbootin-319 directory, I typed:
>cp slack-desc package/usr/install/
14) Change into your package directory
>cd package
15) Become root
>su
16) Type:
> makepkg unetbootin-319-i586-xxx.tgz
where xxx is an identifier. If for VectorLinux 6.0 it should be something like vl6. If for personal use, it is generally taken to be your initials, and which iteration of the package you have tried to build. In my case, this is 1tan. You will see:
Searching for symbolic links:
No symbolic links were found, so we won't make an installation script.
You can make your own later in ./install/doinst.sh and rebuild the
package if you like.
This next step is optional - you can set the files and directories in
your package to some sane permissions. If any of the files or dirs in
your package have special permissions, then DO NOT reset them here!
Would you like to reset all directory and file permissions and set
their ownerships to root:root? [y/N]
17) Select y for yes.
18) You'll see a bunch of makepkg noise, and then if all is well in the world, you'll have a package that looks like this:
unetbootin-319-i586-vl6.tgz
which can be installed via "installpkg unetbootin-319-i586-vl6.tgz".
19) In my case I typed:
>installpkg unetbootin-319-i586-1tan.tgz
and then saw:

Now understand that this method of building the package will not deal with dependencies. Perhaps someone who is a bit better versed in including dependencies could highlight how to deal with this. Also, in my limited research, it seems that one could modify the UNetbootin source to point to the VL 5.9 Live iso for download so that the image would not have to live locally for it to be installed. Also, a *runtime* dependency seems to be 7zip, although the program loaded without it. I have also not yet tried to create a bootable thumbdrive yet. I have only created a package without either checkinstall or vpackager.
Good luck, and happy Vectoring!
