Comment (by thoughtpolice):

 Hmmmm... So, this was an error on my part, but it makes me think of
 something I'm not sure we considered:

  - Right now, if you *don't* have GMP available at build time, and you use
 the in-tree GMP, GHC will link it statically into your applications. That
 is, GHC will build GMP locally to use it, and resulting applications won't
 have a dynamic link to `libgmp.so`.

  - If you have an external GMP at build time, then it will link resulting
 binaries against that. Since GHC self-bootstraps as you can see, this
 includes GHC itself. This happened to me because I did `brew install gmp`
 to test something.

 Adam, I can provide another binary in the mean time with the caveat it
 statically links to GMP. Is this acceptable? For some people I know (out
 of principle or otherwise) this isn't, and they will want to dynamically
 link, so perhaps there should be two for now.

 Frankly, the binary proliferation here is a bit silly almost... we should
 really carefully evaluate what to do with GMP etc in a discussion in the
 future.
