Probably related to https://github.com/eliben/pycparser/issues/147

[d33tah]

@lopuhin: man, you are amazing :3 adding --no-binary pycparser solved it for me.

[lopuhin]

@d33tah you're welcome! Wrote an issue for a better long-term fix.

[d33tah]

@lopuhin could you link to the issue so I could subscribe to it?

[lopuhin]

@d33tah sure, I meant this one #71 - I thought that with wheels pycparser won't be involved, but now I'm not sure, I have to check.
