Yes leo only has a whheel, not a tar.gz. This is unusual and unfortunate,
because pip2tgz needs a source archive of some kind.

I tried pip2tgz on a couple od snapshots, but it always fails with:

    running install_egg_info
    Copying leo.egg-info to /tmp/SBo/package-leo-editor/usr/lib64/python2.7/site-packages/leo-5.7.3-py2.7.egg-info
    running install_scripts
    Traceback (most recent call last):

I can't fix this. Anyone??
