gfortran works from Terminal on MacOS
( which gfortran
/usr/local/bin/gfortran
)
but doesn't from inside MATLAB
mex -v timestwo.F

The PATH as set by the Terminal application may be different than as set by launch an application from the Dock. Try this in MATLAB:
getenv('PATH')
Is /usr/local/bin there?
Now try launching MATLAB from the Terminal window (where gfortran is on the path):
/Applications/MATLAB_R2013a.app/bin/matlab
My guess is that MEX will work if you launch MATLAB this second way.

Thanks, that helped. I put
setenv('PATH', [getenv('PATH') ':/usr/local/bin']);
into startup.m. However, now I get
>> getenv('PATH')
ans =
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
>> mex -v timestwo.F

This is almost certainly an unrelated problem with Xcode 5 no longer shipping the 10.7 SDK (R2013a was released before Xcode 5). For a work-around, see:

Upon setenv('PATH', [getenv('PATH') ':/usr/local/bin']);
I managed to successfully compile timestwo.F
However I got an error while trying to compile yprimefg.F
