pgf-pie package

Dear all,

The licensing situation of pgf-pie is pretty unclear.  I have asked the
author about 3 years ago to clarify it, but it seems that the package
has been abandoned.

I haven't found anything about the MIT license anywhere, but the GitHub
repo contains a copy of the GPLv3

However, this is not the version that is present on CTAN and because
CTAN has this (sorry to be frank) stupid policy that packages can only
every be updated with explicit permission from the original author, it
is impossible to fork and update pgf-pie.  So we are stuck in a
situation where no explicit license has been given (the license *has* to
be bundled with the sources, anything else is null and void) and unfixed
bugs keep piling up.

Kind regards,
