That gem is incompatible with Ruby 1.9 syntax, and you appear to be
attempting to use it under Ruby 1.9.  The problem is that the when
keyword of the case statement no longer allows the use of a colon to end
the match expression.  One must either use the then keyword or a newline
instead.

You should either contact the gem author and request an update, fork the
project and update it yourself, or use the gem under Ruby 1.8.7.  Good
luck! :-)
