[Haskell-cafe] Become a GHC build slave!

[Seth Kurtzberg]

I'm joining this discussion a bit late, but ...

I can provide a build machines for netbsd and freebsd.  I didn't see those on the URL cited below.  They are fairly common, so perhaps I just missed them.

In any event, if netbsd and/or freebsd will be helpful, please let me know.
