At least in the US, collections of other copyrighted works can have
their own copyright and licensing terms. Each of the individual works
also has an independent copyright and potentially a license. The
application of the Non-Profit OSL to the collection does not imply
that each of the components falls under that license, just the
collection. A clarification on the Python(x,y) page would be in order.
The Python(x,y) license cannot place additional restrictions on the
redistribution of the particular GPLed code. It can place restrictions
on the collected work, but if one were to extract the GPLed code from
the collection, one should be able to only deal with the GPL and not
the license of the collection. Or rather, if the license of the
collection attempts to forbid that, then Python(x,y) cannot legally
include the GPLed components as part of the collection.
For example, the official OpenBSD CDs are copyrighted and have
restricted distribution. However, the CDs include GPLed packages like
"I have come to believe that the whole world is an enigma, a harmless
enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
