Perhaps you do not have the zope.interface module installed?

I'm not sure which linux distribution you are using, but I'm guessing  
from the rpm command that it is some RedHat derivative. You can save  
yourself from these sort of dependency problem by using Debian and  
installing MediaProxy2 directly from our repository.
