It will be useful if you can send logs of the errors you are getting.

We have a nightly build on 10.11 that works fine.. [look for lines with 'ipro' string]

One potential pitfall on OSX that I've noticed is - update/install
latest xcode - but not update/reinstall brew [gfortran]. Here - the
old gfortran [from brew] fails with newer xcode..
