An incoming port, www/nuvolaplayer-deezer, will depend on
textproc/py-scour while using 'python:3'. That, as explained in
poudriere#259 , would break PACKAGE_BUILDING (as in
An easy solution to this is to force a Python version (python:2) in
py-scour USES, considering that the port was just added, and no other
port depends on it (thus, there is no current interest in being able
to build it with a specific Python version).
py-scour itself depends on devel/py-six, and the issue might repeat
itself in environments with DEFAULT_PYTHON != 2.7 (custom package
The real solution is to force the build of py-scour with the default
version of Python, thus making sure that - when PACKAGE_BUILDING - it
finds py-six package.
The hack may be removed (and 'concurrent' added) when VARIANTS support
lands into ports.
