Comment (by akkornel):

 I hit this issue, and found that installing python36 +readline (after
 removing py36-readline) got things working again.  That made me wonder:

 * python36 is still telling people to install py36-readline if using
 Python from the Terminal.  Should that be changed to reference the
 readline variant?
 * Should the readline variant be marked as default?  Or is there a way to
 get python36+readline to be cached at Macports even though it's not the
 default?

 I ask the latter question because it may be annoying to users who install
 Python 3.6, only to be told that they have to re-install (with the extra
 build delay) what they just installed, if they wanted to use the Terminal.
