    <p>I'm trying to get Rails 3 installed in my fresh Mac OS X setup but I've got some problems. I'm downloading RVM and installing Ruby 1.9.2 without troubles, but when I try to install Rails using:</p> <pre><code>gem install rails </code></pre> <p>I get:</p> <pre><code>Thomas@~ $ gem install rails /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/config_file.rb:28:in `&lt;top (required)&gt;': uninitialized constant Gem::ConfigFile (NameError) from /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/gem_runner.rb:8:in `&lt;top (required)&gt;' from /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /Users/Thomas/rvm/rubies/ruby-1.9.2-head/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from /Users/Thomas/./rvm/rubies/ruby-1.9.2-head/bin/gem:13:in `&lt;main&gt;' </code></pre> <p>I tried many things; I removed RVM, and reinstalled it, but I'm still getting this error.</p> <p>What I find weird is that RVM is installed in <code>~HOME/rvm</code> and not in <code>~HOME/.rvm</code>.</p> <p>When I stay with my original Ruby version, gem is recognized. Maybe should I create a link somewhere to link gem with different versions?</p>

    3. COMacPort has nothing to do with RVM or installing a Ruby with RVM - I have two Macs with RVM, multiple Rubies installed by it, and neither has MacPorts installed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
