problems running gui samples in pnetlib

Hello List,
I'm having a problem running the gui samples in pnetlib/samples.
I get the follwing exception:

Uncaught exception: System.EntryPointNotFoundException: Entry point was
not found        at Xsharp.Font.CreateFont(String, Int32, FontStyle)
in ./Font.cs:304
        at Xsharp.Font.CreateFont(String) in ./Font.cs:335
        at Xsharp.Font.CreateFromXLFD(String) in ./Font.cs:376
        at Xsharp.Application..ctor(String, String[])
in ./Application.cs:260
        at System.Drawing.Toolkit.DrawingToolkit..ctor()
in ./DrawingToolkit.cs:53

I have my LD_LIBRARY_PATH as:
LD_LIBRARY_PATH=/usr/X11R6/lib/

and I have added a the following link:

ln -s /usr/X11R6/lib/libXcursor.so.1  
/usr/X11R6/lib/libXcursor.so.1.0

as per instructions from the #dotgnu channel but I still have a problem.

Any help would be appreciated.  

Thanks,

Thomas
