mitmproxy-2.7 is not working, due to netlib version mismatch

[th-macports@…]

After doing a port upgrade, mitmproxy-2.7 now complains:

$ mitmproxy-2.7
Traceback (most recent call last):

Of course, activating the old netlib port will solve this for now.

$ sudo port activate py27-netlib@0.13.1_0 ---> Computing dependencies for py27-netlib ---> Deactivating py27-netlib @0.16_0 ---> Cleaning py27-netlib ---> Activating py27-netlib @0.13.1_0 ---> Cleaning py27-netlib

$ mitmproxy-2.7 -v |head -1 usage: mitmproxy-2.7 [options]

In the future, please use WikiFormatting, fill in the Port field with the actual name of the port and Cc the port maintainers (port info --maintainers py27-mitmproxy), if any.
