Use what arpack & atlas variants for use with octave?

OK, I understand that. But there seems to be a catch:
* arpack does offer a +gcc5 variant, yet “sudo port info arpack” lists a build dependency on gcc6.
And as you’ve noticed and as I was already aware:
* atlas has no +gcc6 variant.
Will that be a problem in installing both arpack and atlas (before installing octave)?
