I often build FEniCS on OSX, so it is possible but can be more difficult because of the variability of OSX systems. I'd suggest: 1. Check that you're using the right gmp. From MacPorts it works, but your error message above indicates that your gmp library is not in the default MacPorts location (which is /opt/local/lib) 2. Use the development version (it has some fixes for matching the Python interpreter and libraries) 3. Use gcc in place of clang. Clang can work, but it is tricky when MacPorts uses gcc for some packages.
