[Fedora-haskell-list] ghc-HUnit not present in F-12?

[Bryan O'Sullivan]

Someone reported this recently:

https://bugzilla.redhat.com/show_bug.cgi?id=541372

I tried to see if I could reproduce it on F-12, which I'm now running, but
in fact ghc-HUnit isn't available at all for F-12. I've no idea why, or what
to do about this.
