title: MonoDevelop "The type or namespace 'Android' could not be found"
body: <p>I've mainly been using Mono for Android via Visual Studio, but have switched over to OS X and want to use MonoDevelop.  From the main MonoDevelop menu, I click File => New => Solution.  I select Mono For Android Application, give it a name and leave the location at Users/myname/Projects by default. It creates the shell project with Activity1.cs with the basic Button.  If I try to build or debug the project, all of the using directives error out stating the The type or namespace 'Android' could not be found.  I've googled that exact message and found no matches.  I just downloaded MonoDevelop, all the required SDKs and Mono for Android yesterday on my Mac.  What the heck is going on?</p>
