GHC uses mtl-1.1.1.1 internally, but mtl-2.0.1.0 (added to the HP last

back from http://code.haskell.org/~ross/mtl/ to the master repo on abbot
used by GHC, but that would add transformers as a dependency.  What to do?

Oh, does that mean the HP comes with two versions of mtl?

No, each version of HP has a single version of mtl.  I should have said
that mtl-2.0.1.0 and transformers replaced mtl-1.1.1.1.

Ah, I see, the GHC binary depends on mtl but the GHC package does not, so we don't need to ship mtl with GHC.
