Comment (by awick):

 Just to get things working, I just symlinked my MacPorts copy over to
 /usr/local/lib, for now.

 Personally, I'd much prefer GHC to include an "extra" version of GMP than
 assume the right one is around on a Mac. From my point of view, either
 using a statically linked set of binaries or just including a copy of
 libgmp.10.dylib are equally fine.

 Ideally, it'd be nifty if the installer did a check for a local version.
 If there was one, it'd point the installed binaries to that. If not, then
 it'd have a spare copy it could install for GHC. But I don't know how hard
 that redirection would be, and for now, I suspect just always including
 GMP would be easier.
