Please attach the log.

Sure, done.

​The buildbot sees this problem too.

Any solution yet? Seven months later - same port, same problem.

Another build log that exhibits the same problem

No offence meant, and I understand everybody's busy - but how big a deal is it for the maintainer to add the DESTDIR/destroot to the Portfile?

If it were just that simple! The actual error is:

:info:destroot Installing language specific files for python3
:info:destroot /bin/sh: line 0: cd: ./Lib/python3: No such file or directory
:info:destroot /bin/sh: line 0: cd: ./Lib/python3: No such file or directory
:info:destroot Installing nothing from Lib/python3

so... something is going wrong with the SWIG build system ... maybe it's been fixed on master? Patches welcome!

./Lib/python3 doesn't exist; there is only ./Lib/python
