Comment:

 This is really a Cabal problem. Cabal calls network's configure:
 {{{
 [...]
 ("sh",["configure","--with-compiler=ghc","--prefix=/[...]/.cabal"])
 configure: WARNING: unrecognized options: --with-compiler
 checking build system type... i386-apple-darwin10.5.0
 checking host system type... i386-apple-darwin10.5.0
 checking for gcc... gcc
 [...]
 }}}
 but doesn't tell it which gcc to use, or what flags to pass it. When
 hsc2hs later calls gcc, it calls the right gcc with the right flags, which
 in this case presumably doesn't match the default gcc and no flags.
