>Description:

If you enable the PYTHON option you will get the following error:

*** [pythonmodules] Error code 127
===

PYTHONPROG must be added to CONFIGURE_ENV, else the port will not
be able to find the Python runtime.

=== WARNING ===

Once this is fixed, there is one more poudriere warning which looks kind of
dangerous and should be investigated:

=== Checking filesystem state
list of files present before this port was installed but missing after it was deinstalled)
./usr/local/lib/python2.7/site-packages/easy-install.pth missing
