Most likely, you are linking with a too old version of the gmp library.
Do you get this error at compile/link time, or at runtime/loadtime? In
the latter case, try running ldd on your executable, and will tell you
which libraries it loads.
Note that Rabindra didn't even let us know which version of GMP they
compiled, which command they used for the failing compile, or any other
needed information.
