pkgdb -F stuck

[Rob]

Hi all,

I was in the middle of updating the KDE ports when we had a blackout and my 
UPS wasn't able to keep the box alive long enough.  I have a feeling the 
pkgdb.db is corrupt, because when I try to do anything that touches it, the 
process hangs while updating the pkgdb:

% ps ax | grep ruby
4021  p2  R+   1288:56.99 /usr/local/bin/ruby18 /usr/local/sbin/portinstall -O 
kdebase

Any way to recover this?

cheers,
Rob
