Plugins Gone Wild

I think I messed up my install of Machinist. I tried to install it as
a gem using

             sudo gem install notahat-machinist --source http://gems.github.com

and when that didn't seem to work, I tried

             ./script/plugin install git://github.com/notahat/machinist.git

I think I have a really big mess and would like to remove everything
and re-install.

When I try
       script/plugin remove, my system completes but I don't see
anything going on.

When I tried to remove the gem it says it was unsuccessful.

Help???

I think I messed up my install of Machinist. I tried to install it as

         sudo gem install notahat\-machinist \-\-sourcehttp://gems.github.com

and when that didn't seem to work, I tried

         \./script/plugin install git://github\.com/notahat/machinist\.git

I think I got it all cleared up. I just went in and deleted everything
in the related directories and re-cycled my RadRails. Then I tried re-
installing the gem. ==>Now everything seems to be working. I did find

gem environment and >gem list to get a good handle on where

everything was located and where I was at in terms of my
installations. ==>Apologies to the group for such basic questions.
