Sorry if I'm not being clear. I'm using python.org framework python, 
which supplies its own pip, and its own location for packages: 
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages

In the past, upgrades have never been a problem, so I don't know if 
anything has changed with the latest macOS, or the latest pyobjc, or the 
latest python build, or... And I don't know if the "--ignore-installed" 
solution is a workaround, or actually the right answer.

(I do know about virtualenv, but I don't think that's the route I want 
to go at this point, and I'm pretty sure I shouldn't have to.)

Yours,

Andrew
