I'm not sure if a complete rewrite is needed but it's at least broken.
That's probably because at the time libgmp2 (which libgmp-freebsd is)
was written the sparcv9 support of GCC was in its early stages and
therefore also not really supported by libgmp. The assembly code of
libgmp4 (which works without problems on sparc64) has diverge to
much that one could easily spot how it was fixed and back-port it to
libgmp-freebsd. IMO it's not worth spending time trying to fix
libgmp-freebsd. The right thing to do should be to convert the
remaining ports that depend on libgmp-freebsd to libgmp4 and de-orbit
the former, especially as there are other platforms like ia64 and ppc
that may well be broken with libgmp-freebsd or are totally unsupported
like amd64.
