Comment (by flwyd):

 I'm also getting an error on Mojave (10.14.6).  I first saw this with
 `port upgrade outdated` but the error continues after an
 uninstall/reinstall cycle.  I don't think the `gfortran` message is the
 root cause.  In my log and the log from githubbjs I see:

 {{{

 for architecture x86_64

 }}}

 My first attempt doesn't have a gfortran error, but if I run `port install
 julia` a second time without `port clean julia` then I get the following
 error:

 `gfortran` in the `work/bin` directory is a symlink to `/opt/local/bin
 /gfortran-mp-12`.
