: I saw FreeBSD had some interesting mechanisms for grabbing source code,
: applying patches and/or scripts, and then compiling, etc....
: Is anyone working on a similar system here?

OpenBSD has this integrated into their tree.  With the little poking
around I've done there, I don't see why it would fail to run on NetBSD
as well, modulo missing programs.

I have a version up and limping on Solaris, but it isn't ready for
prime time yes.
