pkgdb and ruby

[Ben Paley]

Hello

Contientiously, I like to run pkgdb -F fairly often, especially if I'm using 
portinstall or portupgrade a lot. Recently I've been getting this:

su-2.05b# pkgdb -F
--->  Checking the package registry database
Duplicated origin: databases/ruby-bdb1 - ruby-bdb1-0.2.1 ruby18-bdb1-0.2.2
Unregister any of them? [no]
su-2.05b# pkg_info | grep ruby
ruby-1.6.8.2003.10.15 An object-oriented interpreted scripting language
ruby-1.8.1_2        An object-oriented interpreted scripting language
ruby-bdb1-0.2.1     Ruby interface to Berkeley DB revision 1.8x with full
ruby-shim-ruby18-1.8.1.p3 A set of Ruby modules to provide Ruby 1.8
ruby18-bdb1-0.2.2   Ruby interface to Berkeley DB revision 1.8x with full

Am I safe to remove ruby-1.6.8.2003.10.15 and ruby-bdb1-0.2.1, and point 
everything at ruby-1.8.1_2 and ruby18-bdb1-0.2.2 respectively? And if so, do 
I still need ruby-shim?

Cheers,
Ben
