[MonoDevelop] Monodevelop 2 alpha generates unexpected errors

[alan]

I have installed monodevelop alpha 2 on opensuse 11. I tried to build a
project that I had coded and run previously using alpha 1 on an ubuntu
8.04 but it gives me errors.  Some of the UI components do not load in
the designer and report -  Load Error:Method not found:Glib.Value..ctor
in red on the designer pane.

Looking at my code this seems to relate to those UI components that have
a frame. Also when compiled they give an error message - Fields cannot
have void type(CS0670) which points to a line something like

private void frame1;

protected virtual void Build(...)
...

in the auto generated code file. So it seems that frames are being
represented as void types when the code for the UI is generated.

So is this a result of moving code from ubuntu to opensuse, or between
versions of monodevelop alpha 1 and 2, or even between different
versions of mono ?

Any expert out there ready to venture an opinion and better still
suggest how I can proceed?
