Thanks to the person who was helping me get x11amp 0.9-beta1.1 working on my slink machine. I just got it working today. I had to compile my own gtk1.2 and gdk1.2 from the sources in potato (debian/rules binary is so nice!) and I removed all other versions of gtk, glib, and gdk which meant recompiling gimp from said potato sources (something I was meaning to do anyway).
After that, I just compiled x11amp as per usual and all was fine. For those not up on the discussion, ldd on the x11amp binary did not report linking libgtk-1.2.so.0 and its friends and x11amp was having problems running that would be expected from problems like that. Thanks for the help! -Dano
