Thanks, Igal!  So when I want to go back to using /usr/bin/ruby and it's 
associated gems, would I just delete the stow directory

    $ sudo stow -d /usr/local/stow ruby-1.8.6p230smartleaf

I am contemplating the solution of just upgrading to Ruby 1.8.7 and 
Rails 2.1 since my project is still in development.  However, from 
reading the forums it looks like there are many plugins that won't work 
with Rails 2.1 and other issues that still need to be resolved.  Any 
thoughts on the upgrade route?
