I had problems with compiling that tarball.
./waf configured barfed:
fatal: Not a git repository (or any parent up to mount point /home)
...
CalledProcessError: Command '['git', 'describe', '--tags']' returned 
non-zero exit status 128


So I used the git repository and switched to version 13:

git tag -l
git checkout Version_13

Now ./waf configure starts, but...
... I'm missing a dependency, libjpeg8-turbo (it's not in Debian).
Where can I get it?

Here's the error:

Thanks for sharing, it seems an interesting project.
