Comment (by Peter.Danecek@…):

 I was looking at different options to solve this, but at the end I am
 inclined to just use the corresponding Macports gcc compiler also for
 compiling the C extensions **and for linking**. This would revert this
 port to the behavior it had before transitioning to the //GFortran
 Recipe//. In the end it should have little effect on the C extensions and
 using `gcc-mp-*` solves the problem with finding `libgfortran` without
 having to deal with `build.env` etc. too much.

 Are there any contraindications for this?
