When installing the gem and running for the first time:
$ textmate
/opt/local/lib/ruby/gems/1.8/gems/wycats-textmate-0.9.6/bin/textmate:53: undefined method `method_option' for TextmateInstaller:Class (NoMethodError)
from /opt/local/bin/textmate:19:in `load'
from /opt/local/bin/textmate:19
I'm using wycats-textmate 0.9.6 and thor 0.9.9.
