Comment:

 It's not easily possible to do it at install time because it all depends
 on how GHC itself was built, not how it's going to be installed.
 Theoretically you could do something I gues to change the rpath (perhaps
 `nix` does this for OS X already) but that seems fragile to incorporate
 right now - plus we need to ensure GHC itself does the right thing once
 this is detected. It sounds like a bit of work.

 I think the better thing to do would be to investigate cleaning up the in-
 tree GMP build to install a `.dylib` which we can fall back on, since we
 need the in-tree build for Windows and generally OS X (as it doesn't come
 along). Linux is not so much of a problem.

 In the mean time - I've updated the binaries for the RC2 download. They
 link statically just like RC1. Do give them a go.
