In the above, you have libpq5 installed on your system but the Ruby gem, ruby-pg, is looking for libpg. To correct this issue, you might want to take a look at the ruby-pg git rep ository here: http://github.com/maxime/ruby-pg-for-ruby-1.9.1rc2/tree/master Finally, I don't know enough about the ruby-pg gem in regards to configuring the Kerberos. -Conrad > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
