Building the ruby-rails3-3.0.5 package fails with:
===> Installing for ruby18-rails-3.0.5
=> Installing gem into installation root
File not found: lib
ERROR:  While generating documentation for rails-3.0.5

rails-3.0.4 did install fine.

>How-To-Repeat:
        
echo RUBY_VERSION_DEFAULT=1.8 >>/etc/mk.conf
( cd $PKGSRCDIR/www/ruby-rails3 && make install)

>Fix:
        
Install rdoc 3.4 or newer and possibly rdoc-data gems.

Maybe these should be installed by default for ruby18.

A short-term fix for the 2011Q1 branch would be to downgrade rails to 3.0.4.
