Comment (by rurban):

 Not only the javascript *.swg files are missing, all support files for all
 languages but python and perl5 are missing.

 `ls /opt/local/share/swig/3.0.12/`

 I'd need it for csharp, java, ...
 The workaround is to copy the relevant *.swg files into such a subdir from
 the upstream git repo.
