title: problem with rails - "Could not find gem 'pg"
body: <p>bonjour dudes.
  i have a small problem with rails.
  today i install rails 3 and decided create a new project.</p>
  
  <pre><code>rails new blablabla --database=postgresql
  </code></pre>
  
  <p>i edited database.yml and paste to it my databases, logins and passwords of postgres.
  my postgresql works on port 5433 (instead of 5432)
  database.yml example:</p>
  
  <pre><code>development:
  adapter: postgresql
  database: devdb
  encoding: utf8
  username: postgres
  password: mypassword
  host: localhost
  port: 5433
  </code></pre>
  
  <p>i just want to start server, or add controller, but rails says:</p>
  
  <pre><code>Could not find gem 'pg (&gt;= 0)' in any of the gem sources listed in your Gemfile
  </code></pre>
  
  <p>but i have 'pg'. i think problem with port, but i dont know how fix problem.</p>
  
  <p>sorry for bad english, and thanks for answers.</p>
