very strange…  
I’m on Vista and updated to Rails 2.2.2 and rubygems 1.3.1 with the  
usual problem there.  
…but that’s well documented…

everything was fine…but then I tried the irb console.  
in every shell I have (netbeans, git bash, windows shell)  
I got this result:

In Netbeans (6.5), while the Rails Console gives similiar output,  
however,  
the Ruby IRB sort of “worked”, but I had to load the environment  
manually.  
…see below…

=======================================================================

Yeah, I used to have to do that…especially in the DOS shell.  
not sure why that changed.

but in this case it doesn’t make any difference.
