It could be that gmp is a bit too old for your platform. This has been
the case on other rarer platforms, and on (all?) 64bit archs. One
solution is to install a native, newer libgmp yourself (from the
vendor), and then add appropriate flags to have ./configure and gcc/ghc
find the library (if it isn't in a standard location).

On Irix I needed:
        export LDFLAGS="-L/usr/freeware/lib64"
        export CPPFLAGS="-I/usr/freeware/include"

        cat >> mk/build.mk <<END

And you may need similar if libgmp lives somewhere other than /usr/lib on AIX.
