portupgrade won't run

[Kevin Oberman]

I am not able to run any of the portupgrade tools. They simply have in
a loop that eats the entire CPU.

I have done portsdb -Uu to update the databases and tried pkgdb -F,
but that fails. Turning on debug, I get:
Exception `LoadError' at /usr/local/lib/ruby/site_ruby/1.6/pkgmisc.rb:5 - No such file to load -- features/ruby18/enum

Is there any reasonable way to recover from this?

Thanks!
