Building Mozilla has the lowest barrier to entry on Linux ? I lost full confidence in that after building Fx 2.0 on FC 5. Failed two time, first I had to get a newer version of the source, 2.0.0.1 was missing a patch, and then I had to manually integrate a second patch that's in trunk but not in the 2.0.0.6 source. And to think I thought initially Fx 2 and FC 5 would more or less correctly match each other by not being the very last, not yet tested, but not too old either. That was after trying with a really old RHEL 3 that did not have the correct gnome :-) (but I lost some time already before seeing it)
