+ the cool factor. SGIs were (and are) "cool", so it's easier to maintain a hobbyist community to go to the work of porting, packaging and maintaining a software repository.
OpenVMS has some, although update frequency isn't as often as Nekoware. Solaris used to have a lot, until Oracle went Oracle on Solaris (but OpenCSW is still around). DEC Unixes likely suffer from BSDitis - NetBSD has an excellent selection of software, and (especially for VAX) BSD is historically considered to be "the UNIX" for DEC. Note that that is pretty much "science by Aristotle" (go into a closet, ponder something for a bit, come out and make a big pronouncement without any verification first), so don't give it too much credence.
AIX is IBM, and IBM is, well, IBM, so don't expect too much there. It's better than OS/400/i or the mainframe OSes, so be happy, I suppose... Groupe Bull still has their freeware collection at

, which is targeted more towards servers (naturally), but exists and is kept updated.
I know of nothing for SunOS 4 or Tru64.
