the last upload (0.5.1-1) was done on Nov 19 and skbio hasnt been in
testing for more than 11 months. if it hasnt reached testing by now,
it must have had several other issues.

sarcasm wont help you make your point.

how did you reach this conclusion? before i reported this bug upstream
(why didnt you do it?) they probably werent even aware of the issue.

I think you have multiple actions you can do:

* actually investigate what the issue is, did you try to do it? you
might also find out the fix is easy and end up submitting a patch
upstream
* engage with upstream to get this fixed by them and backport the
patch to the current package (if they prefer not to release a new
version now)
* skip that test / dont make the build fail if there is a test failure
(for now!). Test suites are made to catch errors, and in this case it
worked! expecting the test suite to pass every time is either
unrealistic or an indication the suite is too shallow. grab
information about the failure and report them upstream, but in the
meantime (since it's a known issue) you can decide to skip the failure

you say you are in a hurry, and yet you decided to waste a whole day
in this blame-game, i'm sure there is much more you can do to fix
skbio.
