Comment(by gale@…):

 That is one of many incompatibilities with Python 3.

 There are a number of breaking changes between Python 2
 and Python 3. One is this. Another is that print is now a
 function and requires parens. There are others.

 In the upcoming version of Python, the string format operator
 % will be removed, in favor of the totally incompatible
 format method. That will break many things in this port.

 The bottom line is that upstream is just not supporting
 Python 3 yet. If you want to take on that responsibility
 until they do, that's great. Otherwise, we may need this
 port to depend on some specific Python 2 version, and
 hard-code all the shell bangs (and other places where
 the python interpreter is invoked) to refer to it.

 Or perhaps we need some enhancement to the
 python_select system that will easily allow a port
 to avoid Python 3 when needed.
