Uh, what?

Not sure what you mean by this.  If you did a parallel install
to /usr/local, what do you mean that you overwrote mono-stable?  The
mono-stable repo should install to /usr, not /usr/local...

As an off-the-wall guess, I'd suspect a compiler/runtime issue with
trunk.  Or something.

Type::op_Equality() was added to .NET 4.0, so if you were using a 4.0
compiler you'd get a reference to this method.  (I have no idea why
you'd be getting a 4.0 compiler, hence my guess that it's a
compiler/runtime issue.)

On a mostly unrelated note, I've discovered that monodoc from the
mono-stable repo is broken, as I get a different error when attempting
to run it:

        * (browser:462): WARNING **: Missing method Monodoc.RootTree::AddSource(string) in assembly /usr/lib/mono/gac/monodoc/, referenced in assembly /usr/lib/monodoc/browser.exe
        Unhandled Exception: System.MissingMethodException: Method not found: 'Monodoc.RootTree.AddSource'.
          at Monodoc.Browser..ctor (System.String basedir, IEnumerable`1 sources, System.String engine) [0x00000] 
          at Monodoc.Driver.Main (System.String[] args) [0x00000] 

This (obviously) makes no sense to me -- how could browser.exe even
build if that member were missing from monodoc.dll?

Looks like an issue for our build mavens.
