This presents an opportunity for me to propose that things installed in 
site-ruby/1.8 be placed in a subdirectory with either a registered name 
(probably registered at ruby-lang.org) or a name guaranteed to be 
unique. Mac OS X uses URI's as names guaranteed to be unique and avoids 
collisions with programs that might confuse the name with an actual URI 
by reversing the URI (i.e, apple.com becomes com.apple). Those without 
their own domains might use permanent e-mail addresses (i.e., 
net.isp@username) or, if the RubyForge people, as an example, implement 
it, RubyForge usernames (i.e, org.rubyforge.username), or something 
similar. This could avoid massive problems in the not too distant 
future.
