Description vladimir.chukharev 2015-12-11 10:31:20 UTC 
Mk/Uses/python.mk has the following description:
#                       USES=python:2           # Use the Python 2 meta port

I understand this as 'use this if your port needs latest python of version series 2.*'. A discussion in bug 205126 reveals that it means actually a need for a symlink python2, while for latest v2 python it's better to use USES=python:-2.7

It seems to me that the description is to be clarified.

Probably, suspicious usages of USES=python:2 are to be found and informed to maintainers. I plan to do this change in all my ports as they are updated.

Thank you for the report Vladimir.

If there's anything else in python.mk that is unclear, let us know, and I'll do my best to improve those as well
Comment 2 Po-Chuan Hsieh freebsd_committer freebsd_triage 2015-12-11 11:41:10 UTC 
IMHO, "USES=python:2.7" is better than "USES=python:-2.7" since we do not support any other versions lower than 2.7.
Comment 3 Tobias Kortkamp freebsd_committer freebsd_triage 2019-01-18 09:27:08 UTC 
Support for USES=python:2 and the comment about it are gone.  Using it
is a DEV_ERROR now, so this is fixed/overcome by events.
