Version number mismatch: inconsistency between gmp.h and libgmp

[Victor Shoup]

This happened to me when installing some other software.
What it most likely means is that you installed GMP in /usr/local,
but that GMP is also installed somewhere else by the system.
The solution is typically to make sure that LD_LIBRARY_PATH includes
/usr/local/lib.  This will ensure that you get the version of GMP
that you are expecting.
