Comment (by jfcaron@…):

 I found a sequence that does something:
 -force activation of the offending port (e.g. py27-pycparser).
 -uninstall offending port.
 -clean offering port.
 -Try to upgrade outdated ports again. Now the same initial error occurs
 but for some other port up the dependency chain (py27-cffi, then
 py27-asn1, now py27-idna).

 I think I am working my way up the whole dependency tree of python27.
 What could have caused this?  Is there a way to short-circuit this chain
 and get back to my life?
