Portupgrade problems

Hey all,

I haven't updated my ports for a few weeks and after after a recent cvsup of 
world and the ports tree I tried to run portupgrade -aCC and was displayed 
with the following:
n /var/db/pkg ... - 318 packages found
(-8 +6) (...)/usr/local/lib/ruby/site_ruby/1.6/ports.rb:4:in `require':

Below are the seg faults caused from above:

dumped)

dumped)
Sep  6 15:08:49 nova kernel: pid 79479 (ruby), uid 0: exited on signal 6 (core 
dumped)

I removed /var/db/pkg/ruby* and portupgrade and reinstall installed them but I 
get the same. Running portversion gets a hang portsdb -uU seemed to work ok. 
pkgdb -F returns:
-->  Checking the package registry database
