nanomsgxx can't find nanomsg on Arch

[Sinity]

Hi. I've installed nanomsg via Pacman, and it works fine. But then I cloned this project, ran ./waf configure, and I've got this:

Any idea how to make it work?

Seems like it's a crash in the internals of waf, what python version do you run this with?

[Sinity]

python yields python 3.5.2 interpreter. I also have python 2.7.12

Same problem here, solved by running python2 waf configure instead of ./waf configure
