The sip/siplib directory has been removed but the source code is still copied.

Has anyone here ever built this project?

[Erhannis]

I'm getting this error, too. Er - I guess I should note I'd checked out an older version, so, grain of salt.

[Erhannis]

Well, I got mine to build - my problems were first that I was doing python build.py build, but should have been doing python build.py dox etg --nodoc sip build. (This doesn't seem to be your problem.)
Also I needed to run pip install -r requirements.txt.

@EnziinSystem please make sure you've installed the version of sip required by requirements/devel.txt for the version of wxPython you're trying to build.
