I have to do a similar thing on OpenBSD, to use an external libgmp
residing in /usr/local/lib. But no real hacking is required!

When compiling GHC, before you start, add something like:

         , "-L", "/usr/local/lib"

to somewhere down around line 137 of ghc/rts/package.conf.in. This way
GHC will always add the -L/usr/local/lib flag when compiling .hs files
and will find whatever library you need.
