MeMe's don't group

I've added about 50 feeds to my MeMeTracker and many contain very similar stories but they aren't grouping together.

I installed python-numeric on ubuntu :
apt-get install python-numeric

But instead of installing Pycluster I installed biopython because in the Pycluster INSTALL file it says:
Biopython versions 1.11 and up also contain Pycluster. There, it is referred to
as Bio.Cluster. See http://www.biopython.org.

For thoes interested you can install it with :
apt-get install python-biopython

I tried to install Pycluster from soure but recieved errors:
