is /var/lib/gems/1.9.0 correct?

Are you using Ruby 1.9.0?

I would recommend you upgrade your version of Ruby to at least 1.9.1
since 1.9.0 was a developer preview of 1.9.x codebase and there are
chances the gem didn't compile properly under it.

Can you post the mkmf.log that exist in /var/lib/gems/1.9.0/gems/
pg-0.10.1/ext folder?

That will help us determine if the extension required by pg gem (that
is part of it) compiled successfully.
