I assume the setup on the builder is foobarred, so that a system-installed libmemcached gets preferred to the one we bundle at link time. Or our checkout somehow gets the wrong codebase.
Probably lack of an rpath. This explains a problem I had too.
Is there anyway around this in the mean time, or are the 64bit centos machines I just set up hosed? (It's just a virtualbox cluster, so not a huge loss, just some hours of my life )
moving to the new codebase, this becomes obsolete
