The alternative is to use static linking of gmp (as suggested by chak) _and_ readline (version 5), so that user programs are also statically linked with these libs.

I just have succeeded in linking ghc-6.8.2 statically with libreadline.a and libncurses.a in the compiler directory by setting:

Readline is distributed under the GPL, not the LGPL (which gmp is). Does the above cause a licensing problem? (I don't have much experience in that area; hopefully someone can explain this issues involved.)

Perhaps the best answer is for someone to make editline bindings for Haskell? I believe this would solve the problem twice: OS X comes with editline, and it's BSD licensed so we can happily statically link against it. The latter may help us on Windows too. Everything I know about editline is third-hand, but AIUI the APIs are very similar, so it shouldn't be hard to alter GHC to use editline instead. Thanks Ian
