[Ironruby-core] IronRuby + Mono + WinForms issue

Wow.  Yeah, I can see why that too awhile! :)

Thanks for the explanation.  I understand the issue here, and I see the
difference between the two versions.

Thanks also for the build script.  That will help a lot going forward.
I'm just about to set up (build) Mono 2.4 on another Ubuntu 8.04
machine, so that looks the business!  Is the whole script available
somewhere?  I know I could probably just finish it myself fairly
quickly, but if you've already got one that works, that'd be very
cool. ;)

I don't really use any other of the default Ubuntu mono apps, but I
didn't want to deal with dependency-hell with apt to try and remove only
what I didn't actually need.  I figured it'd just be safer to build from
source, use the source script to toggle the environment and leave well
enough alone.  I do the same thing to cycle between several versions of
the JDK when I'm doing that sort of thing too, so it isn't a new trick.

What I ought to do is summarize all of this nicely into a blog post, but
I've issues with my blog at the moment.  At least I have the emails, and
I'll likely be going through this again after a while to set up another
machine.  By then, I should have my blog sorted! :)

Thanks so much for all your help!
