There's a small collection of prebuilt packages in ftp.netbsd.org in
the ~/pub/NetBSD/arch/pmax/pkg directory.  If anyone finds them
useful, please let me know.

Unfortunately the package collection (the net.software) doesn't really
understand about ELF on NetBSD yet, so many of the packages don't
build cleanly.  Our package system doesn't try and correct for that.

I hope this situation will improve over time.
