Error loading Mongrel in Aptana Ruby Application on Vista

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

Ideas as to what is going on?

Seems that the support for Ruby 1.9.1 on windows is still not up to scratch yet due to many libraries that contain native extensions is not built for Ruby 1.9.1.

Try using Ruby 1.8.7 on windows, as it has been around for a long time and stable.
