Here's the options I used:
./configure --prefix=/usr --sysconfdir=/etc --mandir=/usr/man --libdir=/usr/lib --bindir=/usr/bin --localstatedir=/var --without-arts
Although you might want to have support for arts, in which case you can remove "--without-arts".
There are quite a good deal of options, so you might want to enable them for specific support.
You only need kdelibs (and ruby, I think). Kdebase does not need to be installed, if you don't want it.
If you already have a previous version of amarok, then you should have the dependencies installed, in which case you don't need to worry as much about going through all the configure options.
EDIT: I compiled this in a not-very-fresh install of VL. That's why I won't be submitting this package to the repos (at least, not until I do a clean install in another partition).
