Howdy Matthew!

I have not seen this before, but netCDF fortran is very sensitive to the build 
environment. The library must be built with the same fortran compiler (and 
settings) that you are using.

Can you try building from scratch on your machine, with your fortran compiler, 
and see if the problem persists?
