Ubuntu hides gems from you!
May 19th, 2007
You might think Ubuntu would put its gems someplace normal, such as /usr/lib/ruby/gems…
Wrong.
It puts them in /var/lib/gems, which explains why the cheat gem doesn’t work when installed. Now I need to add /var/lib/gems/1.8/bin to my $PATH.

not true for edgy. mine were stored in /usr/lib/ruby/gems. after updating to fiesty, they are in the same location.
Totally agree with jherber! And I’m not asking hot it works… just use it!
jherber: Well, you, sir, are lucky! I wonder what determines this…
