 ### Bug report

 Trying to install py36-matplotlib from the current macports (macports
 version 2.5.4) fails, as py36-matplotlib depends on an obsolete package
 py36-pyobj-cocoa.

 Here are macports instructions that demonstrate the problem

 {{{
 % sudo port selfupdate  # updates to MacPorts base version 2.5.4

 **Matplotlib version**
   * Operating system: Mac OSX 10.14.1
   * Matplotlib version: py36-matplotlib @3.0.2
   * Python version: Python 3.6.8  installed in /opt/local/bin/python

 I believe all relevant packages were installed via macports.

 The same bug seems to exist in other libraries such as py37-matplotlib.
