Comment #9 on issue 241 by [email protected]: Tests fail in perl-test harness for 1.4.10
http://code.google.com/p/memcached/issues/detail?id=241
can you try grabbing the tarball and simply doing a ./configure && make && make test ? use script to include the full output of the test run if you can.
I'm sure that centos/redhat don't typically error like that...
