Running the Example notebook fails #21

Closed josephcslater closed 7 years ago

josephcslater commented 7 years ago

I'm on MacOS X, Jupyter 4.3.0, python 3.6.1 and am getting the following on execution of the fortran cell. I can't figure out what this means or how to fix it.

Things were working on my machine some time ago, but thousands of minor upgrades since I last tried and used it so it's infeasible to figure out what might have broke it.

ImportError Traceback (most recent call last)

This appears to be a problem that has happened a few times with gfortran installations on MacOS X. Replacing libgcc_s.1.dylib with one built by macports resolved the issue.
