GPLv2 is not necessarily incompatible with GPLv3. GPL lets the original
author choose how new versions apply to the software. See paragraph 9 of
the GPLv2 [1].

So if a software supplies the phrase "either version 2
of the License, or (at your option) any later version." then I think it
can be used and redistributed under the Terms of GPLv3.

IANAL, that's just how I understand it.
