'portupgrade' is broken by the recent ports tree change

[Yuri]

I just updated the ports tree, and portupgrade now breaks.
There is nothing about this in UPDATING.

# portupgrade -a
/usr/local/lib/ruby/site_ruby/1.9/pkgtools/portsdb.rb:118:in `block (2 
levels) in fill': MOVED file format error (PortsDB::MOVEDError)
         from 
/usr/local/lib/ruby/site_ruby/1.9/pkgtools/portsdb.rb:112:in `each'
         from

fill'
         from 
/usr/local/lib/ruby/site_ruby/1.9/pkgtools/portsdb.rb:111:in `open'
         from
