RSpec installation problems

All,

I’m working on learning rails, but I am having a tremendous amount of
difficulty getting rspec on rails installed. I have blogged about it,
and I was hoping someone might be able to help out. I’m running on
Vista with Powershell as my command prompt.

I would appreciate any ideas.

version of dasBlog, so please try again if a security exception comes
up when you try to access the link above.

All help is greatly appreciated,
