 Of course. isl @0.22 provided libisl.22.dylib. isl 0.24 provides
 libisl.23.dylib. This library version change is why all the gcc ports that
 linked with libisl.22.dylib had their revisions increased as part of the
 [changeset:52cf3d239d60402dcd3843f927810e9b57a7c63f/macports-ports isl
 @0.24 update] and now need to be rebuilt.
