[MonoDevelop] MDB fails to start within MonoDevelop

[BenPence]

I am trying to get mdb-2.0 working in Monodevelop 2.0.  It installs, but
throws an exception when I try to use it.

Setup: 
-mono 2.4.2.2
-monodevelop 2.0
-mono-debugger-2.4.2.1
-monodevelop-debugger-mdb-2.0 (note: when I tried to 'make' this package, I
got the "./RuntimeInvokeManager" error.  I applied the patch found 
http://www.centriment.com/2009/07/26/patch-for-monodevelop-2-0-debugger-for-mono-2-4-2-2/
here , and then it installed.)

mdb works fine from the command line (see test run below)
When I try to debug a program in MD, it compiles successfully, then gives me
the following error in a popup:

Why can't monodevelop use mdb, when the command line version works fine?

Thanks in advance
