You actually do have to do this. The reason is if you uninstall umem then the
memcached port will fail. MacPorts must warn the user if they are uninstalling
a port if it'll break any other ports:
bash-3.2# memcached -v -u root
^CSIGINT handled.
bash-3.2# port -v uninstall umem
---> Deactivating umem @1.0.1_0
---> Uninstalling umem @1.0.1_0
---> Uninstall is removing umem from the port registry.
bash-3.2# memcached -v -u root
dyld: Library not loaded: /opt/local/lib/libumem.0.dylib
Referenced from: /opt/local/bin/memcached
Reason: image not found
Trace/BPT trap
The standard in MacPorts is if you can pick up a dependency upon configuration
time then you either need to specify a dependency upon it in the Portfile or not
list it as a dependency and then tell configure not to find it.
In your case, I think adding a default ac_cv_search_umem_cache_create=no
environmental variable should be sufficient to disable umem. You also may need
to do this for ac_cv_search_gethugepagesizes=no
