However, in the lib directory there is another COPYING file that says GPLv3.  I was trying to figure out what LICENSE should be set to for automake when the sources contain both GPLv2 and GPLv3 code.  Should it be set to something like GPLv2/GPLv3?  I've read that GPLv2 and GPLv3 are incompatible (http://gplv3.fsf.org/wiki/index.php/Compatible_licenses#GPLv3-incompatible_licenses) so can a recipe even be marked as being both GPLv2 and GPLv3?

If the GPLv2 has the "or later version" clause and you are combining
with GPLv3, then there is no incompatibility as the entire thing is
then distributed under the GPLv3. If there is no "or later" clause,
then its a problem that needs to be sorted out upstream.
