in terminal do “echo PATH | pbcopy”.  This puts your path on the  
clipboard.  Now go to TextMate's advanced prefpane, and add a new PATH  
variable in the Shell Variables tab.  Paste in your PATH from the  
terminal, and now everything should work (assuming that python3.0 is  
on the shell PATH).

alternatively, in Terminal do “which python3.0” and use the result  
as your #!.
