After more than two weeks of work, I've been able to commit to the pkgsrc tree all the required changes to bring the GNOME Desktop to its 2.8.0 version.
The update has resulted in 73 new entries added to the doc/CHANGES file; of these, 2 are new packages, 70 are package updates and 1 is a removal of a meta package. Quite a bit, eh? ;-)
Unfortunately, not all the official components that form the GNOME Desktop are in pkgsrc yet; these include gnome-nettool, gnome-system-tools, gnome-volume-manager, gnomemeeting, vino, ximian-connector and evolution-webcal. This is because I have had not enough time to work on them, and I expect they'll carry multiple portability issues. If you want to help, there's always pkgsrc-wip where you can add any of these missing packages!
Now, to install this new and shining GNOME release, just get into pkgsrc/meta-pkgsrc/gnome, type make install and you're done! Oh, and in case you don't know, this is not restricted to NetBSD; you can use pkgsrc even under Linux!
