Comment (by mf2k):

 @michaelld: Would you be willing to update the py-cheetah on your computer
 to version 3 and test your ports against it?

  - py-turbocheetah looks dead because upstream has not been updated since
 2007 and only officially supports python 2.5.
  - py-tahchee: appears to be [ticket:55542 abandoned].

 If michaelld gives the go ahead, let's just update the existing py-cheetah
 port to version 3.
