archivers/py-borgbackup

[Russell L. Carter]

So if I try to build it, I get this:

Finished build of archivers/py-borgbackup: Ignored: you have python 2.7 
set as the default, and this needs 3.5

As an experiment I set PYTHON_DEFAULT=3.5 and reran poudriere and of
course all the 2.7-only ports failed, along with everything that depends
on them.  Just to be complete I have python3.6 installed.

So... how do I build archivers/py-borgbackup with poudriere on a
system that needs 2.7 as default?

Thanks,
Russell
