This will save you from playing with PATH:

   1  sudo ln -fs /opt/ruby-enterprise-1.8.6-20090610 /opt/ruby-enterprise
   2  sudo ln -fs /opt/ruby-enterprise/bin/gem /usr/bin/gem
   3  sudo ln -fs /opt/ruby-enterprise/bin/irb /usr/bin/irb
   4  sudo ln -fs /opt/ruby-enterprise/bin/rake /usr/bin/rake
   5  sudo ln -fs /opt/ruby-enterprise/bin/rails /usr/bin/rails
   6  sudo ln -fs /opt/ruby-enterprise/bin/ruby /usr/bin/ruby

Passsenger.conf is also simplified:

   1  LoadModule passenger_module /opt/ruby-enterprise/lib/ruby/gems/1.8/gems/passenger-2.2.5/ext/apache2/mod_passenger.so
   2  PassengerRoot /opt/ruby-enterprise/lib/ruby/gems/1.8/gems/passenger-2.2.5
   3  PassengerRuby /opt/ruby-enterprise/bin/ruby

This URL contains special characters, which Ruby can’t handle:

   1  >> URI.parse 'http://www.yr.no/sted/Finland/Västra_Finland/Askainen/varsel.xml'
   2  URI::InvalidURIError: bad URI(is not URI?): http://www.yr.no/sted/Finland/Västra_Finland/Askainen/varsel.xml
   3  	from /usr/local/lib/ruby/1.8/uri/common.rb:436:in `split'
   4  	from /usr/local/lib/ruby/1.8/uri/common.rb:485:in `parse'
   5  	from (irb):5

Your browser can probably open the URL. To fix this error encode the URL before handing it to the parse method:

   1  URI.parse(URI.encode('http://www.yr.no/sted/Finland/Västra_Finland/Askainen/varsel.xml'))
   2  => #<URI::HTTP:0x18bfb40 URL:http://www.yr.no/sted/Finland/V%C3%A4stra_Finland/Askainen/varsel.xml>
