Bug#944042: python3-skbio: FTBFS and autopkgtest fail with pandas 0.25

[Rebecca N. Palmer]

Package: python3-skbio
Version: 0.5.5-2
Control: block 931557 by -1
https://ci.debian.net/data/autopkgtest/unstable/amd64/p/python-skbio/3322971/log.gz

Also fails to build; I suspect (but haven't checked) that these are the 
same problem.
