[Haskell-cafe] Build failure for PortMidi on mac: incorrect Block.h

[Brian Victor]

I'm trying to build PortMidi on the mac, and get the error shown below.
It appears that an OSX header is trying to include a Block.h file and
getting the GHC Block.h instead of the one it expects.  I'm new to
Haskell and even newer to cabal, so I'm not sure how to go about solving
this.

Incidentally, cabal, cabal-install, and the system PortMidi libraries
are all up-to-date.
