> the GHC OS X build that Mark used for the newest haskell platform build will work with OS X 10.6-10.1. Doing a binary install of that bindist (./configure --prefix=$brewGHCprefix ; make install; link the executables into path) should be the full extent of the brew formula.

So, If i can recall correctly:
- They could simplify a lot the process if they’d focus on ghc 7.8 only.
- Anyway, they should forget building from source and provide a formula that installs
  the binary distribution.

Am I correct?
