Your right this is probably incompatible. Since TeCGraf, PUC-Rio has the
copyright, a seperate entity from the authors, this might not be perfect for
your situation. This would be a good question for a lawyer. I think we could
bring this up to the opensource licensing guys.. as your one contention
with this license. They would be able to clarify the situation. If this was
a
valid issue, i'm sure they would then be willing to approve the Lua license
as a variant of the zlib/png license.

I'm pretty sure this means you are free to redistribute it, not that
you must distribute it freely. "Permission is granted.." (to) "redistribute
it freely". This is a permission clause, not a restriction clause.
Again, a good question for the lawyers.

Luiz, if you guys would like, i'd be happy to submit these
issues to the licensing board at http://www.opensource.org and post
their response if you guys don't have time for this. Let me know
if I can help.
