New Revision: 443792
URL: https://svnweb.freebsd.org/changeset/ports/443792

Log:
  Specifying an invalid PYTHON_VERSION against its USES should be IGNORED.
  
  The port's own USES may note that is only supports certain versions.  If it
  is attempted to build an unsupported version there's no reason to even
  try.  Rather than giving a WARNING, actually mark it IGNORE.
  
  Currently this should only impact devel/py3-enum34 which does not support
  the default python3 version of 3.6.
