main.log for py27-smmap

[jmroot (Joshua Root)]

3.0.5 was the last version to support python 2.7. ​https://github.com/gitpython-developers/smmap/blob/master/doc/source/changes.rst

Replying to jmroot:

So I guess just pin the py27 sub-port to that version, then? N.B. it can't be just deleted yet, because there are still some ports that depend upon it:

$ port rdependents py27-smmap
The following ports are dependent on py27-smmap:
  py27-gitdb
    py27-git-sweep
      py-git-sweep
    py27-gitpython
