Comment (by lpagani91):

 I did not follow up immediately.
 Cleaning my macport install I stumbled against this problem again.
 I uninstalled python35 and python36 and reinstalled them. Both were OK.
 I installed py35-ipython (and its dependency py35-gnureadline) without
 problem
 but py36-gnureadline install still crashes :
