You can always download/clone it from Github:

git clone
cd covertutils
python install         # this one may need root privileges

It is also available in PyPI, but I cannot guarantee that it will be the last version.

pip install covertutils

Finally, the makefile in the git repo may contain useful commands, like “compile”. It may be wise to give it a look. Try compiling the example code located at examples/ directory in github repo.
