Yes, we can since we do not link against Maxima. We build Maxima with
clisp which is a byte code interpreter, so no funny linking going on
here either. And even if Maxima were GPL V2 you can still stick a GPL
V3 and a GPL V2 binary in the same archive without it violating the
GPL provided either binary does fulfill the license terms of the GPL
V2 and GPL V3 respectively.

If that were the case Maxima *is* GPL V2+.
