I'm brand new at Ruby. Trying to set up the first application/project using Aptana Studio.

Here are my ruby and gem versions

c:\>ruby -v
ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-mingw32]

c:\>gem -v
1.3.6

I am seeing this error below while starting my ruby application. I'm developing on Vista (sucks, I know but am working on changing that)

As a part of fixing this issue, I've installed the following gems and updates
