Rails - Aug 2005 - RubyGems can load my rmagick

I just reinstalled rmagick (for the great new sparklines library). And
now when I try to start up my webbrick I am getting the following
error:

C:\rails\niblits>ruby script/server
c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:194:in
`report_activate_error'': Could
 not find RubyGem rmagick (> 0.0.0) (Gem::LoadError)
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:136:in

        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:161:in

        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:23:in `re

        from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.1.1.1854/lib/active_
support/dependencies.rb:200:in `require''
        from ./script/../config/environment.rb:84
        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in `re

        from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in `re
quire''
        from script/server:42

Does anyone have any ideas on how to troubleshoot this? Rmagick works
- I can do the examples included.

Thanks,

Steve

A little bit more info..

if I run "gems list" it includes
RMagick-win32 (1.7.0)
    RMagick is an interface between the Ruby programming language and
    the ImageMagick and GraphicsMagick image processing libraries.
