No more Ubuntu for me! Too many of my favorite applications (Claws-mail, Pybliographer, Gnucash) ran much better on Gnome, and so I could not switch completely over to Slackware. After much fighting, I think I have what I want now.
Claws-mail was the easiest to get working . . . I think Slackware repositories had most of what I needed. I still don't have Pybliographer, but Kbibtex compiled after adding a patch, so the only thing left to do was fix Gnucash.
It was hard, but not as hard as I expected. I compiled the required bits of Gnome (plus a couple other things), and that was that: a complete Gnome installation is totally unnecessary, and Gnucash looks great under XFCE or KDE.
This list is probably not quite complete, but a useful desktop system probably has most other dependencies (mine did, after all). Unless otherwise noted, I compiled the newest version supplied by gnome.org, available as of 7 July 2007.

Then Gnucash will ./configure && make, sudo make install as hoped.
I realize that the symbolic links are not the proper and elegant way to do things; I did eventually add /usr/local/lib to /etc/ld.so.conf, but the procedure given above got me running. Still no Pybliographer, though, but I think Kbibtex is probably worth giving a try, anyway.
