New description:

 The mono-config file included by devel/gtk-sharp maps 'libgtk-
 win32-2.0.0.dll' to 'libgtk-x11
 -2.0.0.dylib', however an application using Gtk fails to load the dylib.
 This is because it appears to look
 for the dylib in the paths "", "/usr/local/lib", "/lib", "/usr/lib" and
 "." (and then across those paths in
 reverse order, Just In Case.)

 If I set DYLD_LIBRARY_PATH to /opt/local/lib, the dylib is located
 correctly.

 % mcs helloworld.cs -L /opt/local/lib/mono/gtk-sharp -r gtk-sharp.dll -r
 glib-sharp.dll
 Compilation succeeded
 % unsetenv DYLD_LIBRARY_PATH
 % mono helloworld.exe

 Unhandled Exception: System.DllNotFoundException: libgtk-win32-2.0-0.dll
 in <0x000dc> (wrapper managed-to-native) Gtk.Application:gtk_init
 (int&,intptr&)
 in <0x0004c> Gtk.Application:Init ()
 in <0x0001c> Hello:Main ()

 % setenv DYLD_LIBRARY_PATH /opt/local/lib
 % mono helloworld.exe
 (it works)

Comment:

 I've fixed this problem in gtk-sharp and gtk-sharp2, I'll soon attach a
 patch to fix mono.
