Started getting this error after the latest version bump:

This is running on Python 3.6.5.

Thanks for the report. Would you mind trying again. I just pushed a bugfix version to pypi.

Now I'm getting this error when trying to upgrade via pip:

I'm trying to install this in an Alpine 3.6.2 docker container.

[fgregg]

Thanks for the report. I wonder why it's not grabbing one of the manylinux wheels? Anway, I'll include that header file in the sdist.

[fgregg]

What version of pip do you have?

[mumumumu]

I was on pip 10.0.1 when I tried installing earlier. Tried again just now on pip 18.0 and got the same error.

[fgregg]

Okay, pushed a new version. I still don't understand why it didn't use the manylinux wheel, but that's a separate problem.

[mumumumu]

New version is installing without a hitch. Thanks for all the help!
