I want to use tkcalendar and dateentry in my application but have problems
with tkcalendar's dependency on babel and setuptools.
When I try to build babel it fails:

I've being asked not to use external links for code sharing to the
groups but when I paste the code in to my vim editor I do use with slrn
client the code is just messed up.
