I’m running Ruby 1.8.7, Rails 2.3.2, and Gem 1.3.4

I’m a newb, so bare with me… I’m reading Simply Rails 2. The book  
tells me to enter:  
$ rails shovell

Then,  
$ sudo gem install mongrel

Then,  
$cd shovell  
$ruby script/server

However, when I type in that last bit, I get:

LOTS OF STUFF/.gem/ruby/1.8/gems/hpricot-0.8.1/lib/fast\_xs.bundle: [BUG]  
Bus Error  
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9.7.0]

Abort trap

I have no idea what to do from here. I’m thinking being able to run the  
server is kind of important.

I think I really screwed something up. I deleted hpricot gem but I’m  
not sure how to reinstall it. Then, I tried to reinstall ruby, rails and  
gems which seemed to work a bit better. When I type $ ruby -v, it now  
returns ruby 1.8.6 (2008-08-11 patchlevel 287) [universal-darwin9.0].  
Then, I went threw the steps of installing rails, gems, and SQlite  
according to “Simply Rails 2.”

Now, I get to: ~/shovell $ \> script/server  
and then nothing happens. I just wait for the server to load.

Is there a way to reinstall ruby, rails, gems, and SQlite? Or is there  
a way to get my computer back to the state of 4 days ago? I think I  
really screwed something up when I tried upgrading to Ruby 1.8.7.

\*\*I forgot to mention, I’m also using macOSX Leopard.
