As an optional package it is no problem at all for Sage.

We should switch to gfortran, or just making the user have gfortran as a
prerequisite.

Yes, that's a good idea. Alternatively, spend some time and design/write a
little "optional spkg dependency system" for Sage! We've been needing
something like that for ages.

Thanks! And thanks Randy for supporting this.
