[Mono-list] Windows Forms App under Mac OS X Mono

[jeff clausius]

As mentioned it was already there.  The following will fix that problem:

change
/Library/Frameworks/Mono.framework/Versions/Current/etc/mono/config and
modified the entry to the full path of /usr/X11/lib/libX11.dylib.


Now, running 'MONO_MWF_MAC_FORCE_X11=1 mono yourapp.exe' generates a
similar error I was seeing under 2.10.9 as well:

Gtk not found (missing LD_LIBRARY_PATH to libgtk-x11-2.0.so.0?), using
built-in colorscheme

Unhandled Exception:

So, I don't get it.  If I run "port installed", I can see gtk2 is
installed and active.  I can also see libgtk-2.0.dylib in
/opt/local/lib.  What does this code path within mono expect to find?
In what dir?  What GTK library file?  Is it really looking for some file
named "libgtk-x11-2.0.so.0?" on disk?

As always appreciate any suggestions.
