Yes, you're right.  With the upheaval (again) of the interpreter, things
will be a little flakey for a while.  Furthermore, we're phasing out the
4.09 branch (before-ghci-branch) before we get into merge hell.

However, building the HEAD with 4.08.1 should work.

Sorry about the recent instability guys - I'll try to make sure things
settle down ASAP.

Cheers,
