Incompatible library version - rlibmemcached.bundle

Hey there!

I'm running 1.8 of your gem and am encountering a curious issue I haven't been able to debug. Here's the output:

I've nuked my rvm/ruby, reinstalled gems, pristined them, reinstalled memcached, all to no avail. Have you encountered this before? Any idea why rlibmemcached would be the wrong version?
