Hi, it seems Guppie (using version 0.35.5, since its default in ximian gnome, and since 0.40.x failed miserably on me) is having some problems with libglade. it tries to inlcude glade/glade.h, but in the newest gnome 1.4.x versions, you need to add -I/usr/include/libglade-1.0 to the compile to make that work.
