You would.  RMS says the AFL and the GPL are not compatible; he doesn't say
exactly why, beyond noting that there is more than one problem.  The patent
provision is the obvious candidate, however, based on RMS's review of the
IBMPL.  Note that RMS reviewed AFL 1.1 and the current release is 1.2,
but there is no reason to think he would have changed his mind.

As the AFL's preamble says, just put the line:

	Licensed under the Academic Free License version 1.2

just after the copyright notice.
