title: Monotouch Binding project build errors
body: <p>I am getting the following errors when trying to build a bindings project. The information is a bit cryptic and I am not sure what is broken/wrong.</p>
  
  <blockquote>
    <p>Error CS0117: <code>MonoTouch.Constants' does not contain a definition for
    </code>NimbusLibrary' (CS0117) (MonoTouch.Nimbus)</p>
    
    <p>Error CS1502: The best overloaded method match for
    `MonoTouch.ObjCRuntime.Dlfcn.dlopen(string, int)' has some invalid
    arguments (CS1502) (MonoTouch.Nimbus)</p>
    
    <p>Error CS1503: Argument <code>#1' cannot convert</code>object' expression to type
    `string' (CS1503) (MonoTouch.Nimbus)</p>
  </blockquote>
  
  <p>I notice sometimes that when I close and reopen the project, then rebuild, the error messages don't appear immediately, but shortly after, they come right back.</p>
  
  <p>Any ideas? Let me know if you need the source for my bindings project.</p>
