borgbackup @1.0.11: Fails to run because of missing 'msgpack-python>=0.4.6'

[uhkeller]

When trying to run BorgBackup, even with no arguments, it fails with the following traceback:

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'msgpack-python>=0.4.6' distribution was not found and is required by borgbackup

py35-msgpack @0.5.6 is installed. There is a BorgBackup bug report (​https://github.com/borgbackup/borg/issues/3889) mentioning that BorgBackup is looking for the old name of the package (msgpack-python), and that MacPort's BorgBackup package would have to be patched to look for the package under its new name (msgpack).

Sorry if I'm missing something obvious here, I've only started using MacPorts.
