>Description:
The pkgdb command of the portupgrade port fails when used with the "-s" option:

raven# pkgdb --substitute=/p5-HTML-Parser-3.45/p5-HTML-Parser-3.51/
break from proc-closure

That's a pretty poor error message.  However I dug around and did this:

raven# ruby --debug /usr/local/sbin/pkgdb --substitute=/p5-HTML-Parser-3.45/p5-HTML-Parser-3.51/

/usr/local/lib/ruby/site_ruby/1.8/pkgtools.rb:7 says:

  require 'features/ruby18/file'

So it's my guess that pkgtools are relying on Ruby components that aren't installed by default.  I'm not a Ruby expert though.

I have ruby-1.8.4_6,1, installed from the ports collection.  And the offending file belongs to portupgrade:

raven# pkg_info -W /usr/local/lib/ruby/site_ruby/1.8/pkgtools.rb
/usr/local/lib/ruby/site_ruby/1.8/pkgtools.rb was installed by package portupgrade-2.0.1_1,1

Try using pkgdb -s
