Help with gfortran

[Pedro Giffuni]

Hi;

I had a try at resurrecting the long-ago-extinct elmer-fem port.
WIP:

https://people.freebsd.org/~pfg/ports/elmerfem.tar.gz

Unfortunately I seem stuck in an error:

This is FreeBSD 10 and I don't have gcc46 installed.
I took the time to rebuild blas, lapack and arpack, which are dependencies.
Any idea what is going on and, most importantly, how to fix it?

Regards,

Pedro.
