===============================================================================
WARNING : CPython API extension could not be built.

Exception was : CompileError(DistutilsExecError("command 'cc' failed with exit status 1",),)

If you need the extensions (they may be faster than alternative on some
 platforms) check you have a compiler configured with all the necessary
 headers and libraries.

@ExplorerOnTheMoon: Do you have the nanomsg C library compiled and installed on your system? It doesn't seem like nanomsg-python bundles or installs it automatically.
