 Hello,

 I tried to install py36-ipython (python-3.6 is installed and working) but
 failed.
 The first time it failed (repeatedly) on the last dependency installation
 (py36-wcwidth).

 Opening XCode, it asked me to update some features. I did.
 I reinstalled XQuartz behind, to be sure.
 I reinstalled Macports itself, selfupdated, and upgraded outdated
 then I tried to install py36-ipython again and it failed at the first
 dependency installation (py36-gnureadline)! while it did not before!!!

 I am lost...
