atlas build fail -- Xcode can't create dynamic library?

[Zippyzip]

I can't manage to build standalone atlas (+gcc5). ( It seems +nofortran avoids the error but then I get problems for atlas dependent ports such as Octave)

MacOS X: El Capitan 10.11.6

XCode: 8.1

Macports: 2.3.5.

Snippet of presumably relevant part of the log file:

My apologies, it seems the problem is not related to Xcode but to gcc/gfortran. I still don't understand why libgfortran is a dead symlink on my installation, looking into it.

Update:

I solved the problem with the dead symlink by reinstalling libgcc. Since then atlas appears to build without problem. (I am still unsure what the deal was with the first error involving XCode, but apparently it does not break the build...)
