Need help finding root cause of staging errors related to MANIFEST

[John W. O'Brien]

Hello all,

At some point between 2017-01-17T07:39:59-05:00
2017-01-23T10:48:15-05:00, some ports started failing to build under
python3.4 (not 3.5 or 3.6). The failure occurs during the poudriere
stage phase while processing the MANIFEST.in template. If the manifest
contains a graft statement that refers to a non-existent directory, the
build log contains a fatal error where before there was only a warning.

The two examples I know of directly are math/py-pandas [0] and
devel/py-ipython_genutils [1].

The time interval implicates python 3.4.6, and not setuptools 32.1.0.
I'm having a hard time narrowing it down further than that.

Can anybody else reproduce this error or an equivalent one? Any ideas
about its root cause?

Thank you,
