problem building with conda

[fgregg]

Hi, I don't know if you are interested in supporting conda, but one of my users reported a failure to build python-crfsuite with conda

Running setup.py install for python-crfsuite

This looks like another incarnation of https://github.com/scrapinghub/python-crfsuite/pull/46 and https://github.com/scrapinghub/python-crfsuite/pull/45.

Latest release is now available in the conda-forge channel: https://anaconda.org/conda-forge/python-crfsuite

I think the issue is still valid - likely you still can't install python-crfsuite to conda enviroment using pip. But as python-crfsuite is available on conda-forge and it is documented in README how to install it (thanks @rolando for both), I'm closing this ticket.
