Also note that gmp.h will not be found without:

export CPATH=/opt/local/include

This directory should be part of the "include-dirs:" for the rts package. And again the file /opt/local/include/gmp.h could be simply copied to <prefix>/lib/ghc-6.10.1/include/

Hmm...Okay, so how do I add a path to include-dirs? In my case <prefix>=$HOME, so I looked under ~/lib/ghc-6.10.1 and I didn't see any files I could modify to change it.

I would suggest to only copy libgmp.a and gmp.h, because the file to edit it <prefix>/lib/ghc-6.10.1/package.conf. Search for (package) "rts" and the fields "libraryDirs" and "includeDirs". But if you mess up this file, all may be lost (so back it up first).

I created a backup, then made the edits you suggested and the build failure I was seeing went away. Thanks!

Was it an option I missed when I was doing the configure for the install?

I'm not sure what configure options to pass (before my building or your installing)

Hopefully someone like Ian can comment here. Thanks, Jason
