Well, I'm not into gnome, but I just finished updating KDE. In my last bulk
build, which finished earlier this week, gnome and KDE built just fine. I'm
not sure  you don't have a local problem.

Note that 'cvs update' will not mysteriously fix things if you have a
broken tree to begin with. Modified files will not be overwritten, for
example, and if you managed to get *part* of your tree branched or tagged,
it won't automagically fix things.

They work both.
