While trying to figure it out (since citeproc-py isn't a direct dependency for me), it seems that todays release of rnc2rng is the issue. One hint pointing at this: I could only reproduce it locally when I went with --no-cache-dir option for pip. Worked perfectly fine before.

I was misguided by lack of release on github -- didn't realize that new rnc2rng was actually released (https://github.com/djc/rnc2rng/issues/27). Would need to figure out if bug is in citeproc or rnc2rng. Meanwhile could be mitigated by removing duecredit from dependencies -- it is very optional (gy -- I thought that this is datalad issue ;))

FWIW, just pushed 0.5.1 release with e600cefe97e12c65fcfecedd5bad45f190ccf81e which blacklists 2.6.2 and also comes with a (then forgotten) .whl. I think this should mitigate installation problems for now. Proper fix is yet to be worked out. Also, strangely enough (yet to investiage) -- this run of python setup.py sdist did generate and included citeproc/data/schema/csl.rng, whenever the one I had uploaded for 0.5.0 didn't.

That seems to work. Thanks much, @yarikoptic!
