It's not necessarily that obvious.  Because Ruby and RubyGems seem to be 
installed in a strange place (/usr or /usr/local is typical),  it's 
likely that the "radiant" command is not in your PATH environment 
variable.  First, try this command:

$ which radiant

If it returns nothing, then it's not in the path.  Because RubyGems 
seems to be installed under /var/lib/gems, try looking for the command 
under /var/bin.  If it and any other gem scripts are there ('rails' or 
'spec' for instance), add that to your path.  You'll probably need to do 
this in ~/.bash_profile or ~/.bash_login or ~/.bashrc, whichever your 
system uses.  Add this line:

export PATH=$PATH:/var/bin

Then you should be able to run the 'radiant' command.  As today is 
"Radiant Day", I'll be in the IRC room most of the day.  Feel free to 
bring your question to me there!
