Here's how to go from a rubygem's source code in a git repository to an installed gem on your machine: 1. Make sure you have git installed. Install MacPorts, then do 'sudo port install git-core'. 2. Copy the git repository to your local machine: <em>git clone http://github.com/gwynm/mailtrap/tree/master</em>. 3. Now you have a new directory, "mailtrap". <em>cd mailtrap</em> 4. Build the gem: <em>rake gem</em>. This step fails if the gem you downloaded isn't using "<a href='http://www.nimblecode.com/articles/2007/01/10/packaging-your-first-gem-with-hoe'>hoe</a>", a gem which builds gems. 5. Install the gem: <em>sudo rake install_gem</em>. 1 2008-03-31T12:07:25-04:00 128 2008-05-01T07:11:22-04:00
