I could not reproduce this on Linux; however, it seemed not to run the swig tests there at all.

Sounds like something is broken with your swig installation. 3.0.12 is new enough. But SWIG is complaining that it can't find go.swg, which should normally be available in INSTALLDIR/share/swig/3.0.12, in your care presumably /opt/local/share/swig/3.0.12. Your SWIG is installed in /opt/local/bin; did you install it yourself? Where did it come from?

It came from MacPorts, some other piece of software thought that it needed it.

"Workaround": sudo /opt/local/bin/port install swig-go

So perhaps the swig test could be a bit more discriminating, but the workaround is an easy one.

I also hit a problem like this on one of our systems. I didn't dig into too much but it looked like the swig install didn't agree with what the test required. I agree with the last comment by @dr2chase, the test could be more discriminating.
