Yes, libmemcached was installed before base was updated to 2.2.

Port rev-upgrade seems to think so. Deactivating gcc46 caused rev-upgrade to consider libmemcached broken and proceeded to install gcc46.

How would I test if the linking is due to the .la files I've been hearing about?
Do I add "delete_la_files yes" to the gcc46 Portfile and rebuild gcc46?
