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]. --snip-- | Each version is given a distinguishing version number. If the Program | specifies a version number of this License which applies to it and "any | later version", you have the option of following the terms and conditions | either of that version or of any later version published by the Free | Software Foundation. --snap-- [1] http://www.gnu.org/licenses/gpl-2.0.html 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.
