Installation fails about howdoi

[gleitz]

It appears that lxml is having trouble installing on 64 bit Windows. I would file an issue with that project and perhaps check out the solution proposed here.

Specifically, I think you need to install lxml from this repo.

I'm going to close this issue. Please re-open if you are still having issues.
