I've built Gnome 2.5 from CVS again, and came across a bunch of auto* tools borkages (and I indeed have a screwed up system, but I'm so lazy to actually reinstall everything, that I keep living with it). The tool for the job, just like last time, was JHBuild, which was reorganized not long ago, so I updated my patch for it to build in a directory different from checkout directory.
Btw, has anyone actually built GnomeMeeting? It's in such a crappy state, and one was supposed to be able to test it — after all, it's included in Gnome 2.6 due for March 9th. Huh.
Oh yeah, jhbuild had epiphany-extensions in the default desktop, and missed dasher, so I need to build the latter. Hope I don't forget.
