ports-mgmt/portupgrade-devel-20091029 fails to install new x11/kde4

[Edward Sanford Sutton, III]

  I have tried pkgdb -fu, portupgrade -f ruby, portupgrade -f ruby18-bdb, and 
rm /var/db/pkg/pkgdb.db /usr/ports/INDEX-*.db, but only portdowngrading to 
previous version has the command not failing. I installed net/kdenetwork4 
before attempting to install kde4 (which i selected all options for). If I 
can include any other configuration details or test other ideas, let me know. 
I have about 1450 ports installed on this machine so I haven't included that 
list until specifically asked for. Included below is a sample run with 
failure:
