I've added a simple "FIXME" comment to that line, similar to how the
other haskell.scm packages do it. The reason is that the ghc-* libs
needed to enable testing haven't been imported yet. I've attempted to
fix that, but got tangled up in conflicting dependency versions and
gave up for now.

Also fixed.

Sure, you'll find it attached.
