I no longer use Linux for development, so I can't easily check, but I suggest after you checkout from git, you first do 'make distrib' to create a tarball, and then install from that tarball.

[matkoniecz]

Thanks for the reply! Is make distrib supposed to need sudo?

# Erase previous directories to make sure we're clean.
rm -rf dist
rm: cannot remove 'dist/Mnemosyne-2.6.1-py3.5.egg': Permission denied
makefile:99: recipe for target 'distrib' failed
make: *** [distrib] Error 1

[pbienst]

It is, if it needs to delete directories which were previously created with sudo :-)
