The work as a whole must be distributed under the terms of the GPL.
However, Jeremy's code can be under whatever license he wishes as long
as it is compatible with the GPL. If he chose the modified BSD license,
one could take pieces of that code, inasmuch as they are separable from
PyQt, and incorporate them into matplotlib. Just because the
BSD-licensed code is combined with GPL-licensed code doesn't mean that
the BSD-licensed code is not BSD-licensed.
Or if he feels like avoiding this silliness, Jeremy could, if he wanted
to, just separately license the bits that other people want to use in
BSDish-licensed, non-PyQt projects.
