Cabal install fails using default osx 1.7 haskell-platform

[ghost]

Using the pre-installed binaries for ghc (7.0.4) and cabal (1.16.0.1) the install fails with:

$ cabal install hdevtools

hdevtools relies heavily on the GHC API, which goes through major changes with each new release of GHC.

Currently hdevtools is tested with GHC versions: 7.6, 7.4, and 7.2

A quick look at the docs for GHC 7.0.4 shows that it is missing several functions that hdevtools uses (such as printException, which is listed in one of your build errors).

Making hdevtools compatible with GHC 7.0 is something that I currently have no immediate plans for, but patches would be welcome (provided that they don't mutilate the source of hdevtools too much).

I suggest that you install the current version of the Haskell Platform (2012.4.0.0) which comes with GHC 7.4.2.
