[geeks] Building on OpenSolaris vs Solaris 10

[velociraptor]

Tossing a couple of oddball q's out there.  Hoping some of you might
have some pointers...

I'm running Solaris 10 on my NAS at home, which presents some issues
as to software.  For the most part, blastwave packages are fine for my
purposes, but I'm having some trouble with a couple of things, and
would like to "roll my own" (vlc, mplayer & friends, bittorrent
client).

So, anyone have any info and/or pointers on using spec files from
OpenSolaris in a build environment on Solaris 10?  Alternatively, is
it possible to run OpenSolaris in a container (branded, maybe?).

Thanks--
