You will need to install libyaml-devel from the epel repositories (which you will also need to add).

For example, are you running CentOS-6 or 5? What point release? Are you using the stock PostgreSQl install, have you installed a different version from another respoitory, or have you built PostgreSQl yourself? In any case what version of Postgres? Providing that you are running CentOS-6.x; and assuming that you are evidently not using the Postgres provided with that distribution; and guessing that you are likely using the pgdg-91-centos.repo; and also guessing that you are using either rvm or rbenv then you likely need to do something akin to the following yum install postgresql91-devel libyaml gem install pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config HTH -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
