[MonoDevelop] Gtk-Sharp issue

[jreineri at mindspring.com]

I just did a clean install of Monodevelop 2.0 Alpha 2 on Fedora 10

Then the folowing:
  yum install monodevelop
  yum install gtk-sharp

I created a new solution with a Gtk# 20. Project.  Then simply did a build.
I get: "Type or namespace 'Gtk' could not be found."

When I created a 'Gnome# 2.0' project I got the same result, except that there was an additional error:
'Type or namespace 'Gnome' could not be found.

I am very new to the Mono environment on Linux and Monodevelop, but have worked in the MS .Net world for a while.

I do understand that these errors are telling me that the compiler cannot find the libraries in question.
But, I do not understand why these system libraries are not locatable.

I find that folloing references defined in the proj file:

    <Reference Include="System" />
    <Reference Include="gnome-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />
    <Reference Include="gtk-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />
    <Reference Include="gdk-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />
    <Reference Include="glib-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />
    <Reference Include="glade-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />
    <Reference Include="pango-sharp, Version=2.4.0.0, Culture=neutral, PublicKeyToken=35e10195dab3c99f" />

What am I missing?

Thanks in advance,
