[Mono-osx] libgdiplus with MonoMac

[Clay Fowler]

We're using the drawing bridge to do libgdiplus drawing in custom Cocoa
views (which is *wonderful*), and everything works great when run from
MonoDevelop. But when trying to run the app bundle outside of MonoDevelop we
always get some variation of the problem below when we call
NSApplication.InitDrawingBridge() (it looks like libgdiplus wants to find a
function called uname in libc, but Mono can't find libc.dylib):

Mono: DllImport loading:

Any ideas?
