import error

Hi,

It seems that I have installed the MemSurfer, but I am getting the below error while importing the memsurfer. A similar issue has been reported previously (https://github.com/LLNL/MemSurfer/issues/3), and I am not sure how to implement the corresponding changes in the new/current setup.py file. Please find the attached setup.py file. I tried to add the 'GMP libraries as suggested in issue #3; still, it didn't solve my issue. I am new to python, and any help will be appreciated.

Thanks.

Start with setup.py and the native extension imported by memsurfer/memsurfer_cmod.py; reproduce the failure using examples/ex_simple.py and inspect the reported _memsurfer_cmod.so import error. Compare the current setup with the changes discussed in issue #3. Done means a clean installation can import memsurfer without the undefined-symbol or missing-module errors.
