 I'm running into the same problem when trying to build ghc HEAD under OS
 X.  In my case, I have some of the requisite libs under
 /opt/local/{include,lib} since I use MacPorts to install them.  The ghc
 build system fails to find them for the above reasons.

 I tried to work around this by adding the following to ~/.cabal/config:

 {{{
 extra-include-dirs: /opt/local/include
 extra-lib-dirs: /opt/local/lib
 }}}

 This seems to have no effect on the build.  Does the in-place cabal not
 look at that config file?

 More to the point, is there any way to pass in those dirs as defaults for
 the entire build?  I.e., a way to add to ghc's in-place cabal's default
 search paths?

 Thanks!

 PS: I do have a very ugly workaround: symlink all required headers and
 libs into dirs on gcc's default search paths.  This is very fragile and
 error-prone, however, and I would rather not do that.
