Building the “text” library fails on OS X Mountain Lion
===

I'm trying to build the `text` library on OS X 10.8 (Mountain Lion) but I get the following erros:

I am using GHC 7.4.2. The following versions of gcc/llvm-gcc are installed (through XCode's command line tools):

`gcc`:

Any pointers to what the problem can be? Can anyone else build `text` on Mountain Lion?
