py35-nbconvert @4.2.0_0 always breaks due to missing entrypoints dependency

[wichert@…]

The current nbconvert ports are unusable. Trying to run nbconvert gives this error:

Traceback (most recent call last):

​entrypoints is a new dependency for nbconvert, but currently not part of macports.

entrypoints has been added, but does not work with python2.7 because it also requires configparser-3.3 to backport python3 configparser functionality. Installing configparser via pip fixes for now, but configparser should have its own port.

Thanks!

This appears fixed
