I just installed Vector 5.8 standard and I have the above problems. gslapt saying that xfce is not installed and, among other things, slapt-get --upgrade says it can't install new xfce because of missing deps. I added the cd as source for packages, it didn't fix anything. Is slapt-get rather broken or somebody removed important packages from the ftp or what ? It's true that I selected not to install a lot of the optional stuff but still shouldn't slapt-get be able to get what it needs ?
Damn- just saw that one of the things it says it is needed glib2 >= 2.12.10 is not on the ftp at all.

Same thing with gtk2. Is there another source I need to add or is 5.8 standard no longer supported or something ?
Output from slapt-get:
root:# slapt-get --upgrade
