Apart from the licences themselves in share/licenses! There is a
potential issue with packages that use an Artistic licence (the quoter
seems ignorant of the fact that there are more than one), but that applies
to any package license other than GPL2 and is the responsibility of the
package owner to check.
Also, some files in share/perl are 'under the same terms as Perl itself',
that is Artistic or GPL.
