 "Configuring integer-gmp") as the local GMP cannot be found (since it is
 installed to /usr/local) just because the missing --with-gmp-* options in
 the configure script.

 So it's surprising that it works there.  As you say, probably just lucky.

 Simply adding "--enable-shared" will not help (I tried it in many
 different combination, but I reserve the right to be wrong), I think it
 needs a ghc.mk file similar to libffi's.

 Exactly - that's what I meant by "I imagine there are related build system
 and installation fixes required".

 So the point remains: the build system for the in-tree GMP library needs
 to be fixed for shared libraries.
