Downloading cmakelang-0.6.13.tar.gz and exctracting it shows that the folder 'cmakelang' is indeed missing. I tried installing through pip straight from GitHub but that resulted in a different error:

The only way I could get it to install correctly was to clone the Git repo manually and run python setup.py install .
