Hi Igal,

Are you sure these are the right steps for installing gems for the 
Smartleaf patched interpreter?  I've followed all your steps outlined 
below, but when I get to

  sudo /usr/local/bin/gem install rake --no-ri --no-rdoc,

the command is not found.

i.e.,
[Cheri@localhost rubygems-1.2.0]$ sudo /usr/local/bin/gem install rake 
--no-ri --no-rdoc
sudo: /usr/local/bin/gem: command not found

I don't think I'm installing RubyGems in the right directory path.

Thanks in advance for your help.

- Cheri
