Hi Don, You're hitting a fail in the testsuite of GMP. The testsuite of GMP can be quite picky. It's not the first time we have seen it fail. And this case is known: https://gmplib.org/list-archives/gmp-bugs/2014-April/003451.html
The quickest way around this is to disable the testsuite. You can do this by adding: runtest=False to the easyconfig of GMP. Beware that the easyconfig you have chosen is one that uses the dummy toolchain. Normally, we use a easyconfig with an EB build compiler. More about that at http://easybuild.readthedocs.org/en/latest/Concepts_and_Terminology.html#dummy-toolchain Ward
