------------------------+----------------------------
 Installing py36-gnureadline causes python3.6 to crash.

 Without py36-gnureadline:

 {{{
 $ port installed py36-gnureadline
 None of the specified ports are installed.
 $ python3.6
 Python 3.6.0 (default, Dec 28 2016, 22:59:42)

 With py36-gnureadline:

 {{{
 $ port installed py36-gnureadline
 The following ports are currently installed:
   py36-gnureadline @6.3.3_1 (active)
 $ python3.6

 Curiously, this problem does not affect ipython:
