We definitely favor fastri, because it's so much more accurate.   
However, the command is suppose to work without the install as well.

I'm not sure how you lost the fastri install.  It lives in Ruby's lib  
directories with other gems you have installed, so it shouldn't  
randomly vanish without outside help.

About the only solution I dream up is that you could have two Ruby  
installs on your machine and something changed to affect which one  
TextMate uses.  You might try typing the following in a TextMate  
document and pressing control-R on that line to see if it's using the  
Ruby you expect it to:

   which ruby

I admit that I'm totally guessing there though.
