# TEMPORARY: There is a problem with the Gnome interface. Gnome should be
# omitted by default until this is resolved. Giving an explicit "--with-gnome"
# flag should still enable it, though. The bug that I'm encountering is that
# the -lgnorba library contains unresolved references to "gnome_init" and
# "gnome_init_with_popt_table". This started showing up after I upgraded my
# computer from SuSE 6.3 to SuSE 7.0.
