I was hit by this as well a week or two ago, but was too tired and
annoyed to investigate the root of this issue, so what I've done was a
stupid, yet effective workaround -- I commented out msgpack-python line
in /usr/lib64/python3.6/site-packages/borgbackup-1.1.7-py3.6.egg-info/requires.txt
file and things were functional again.

But now I got curious and looked around a bit.  Here's what I dug up:
the problem here is that borgbackup requires msgpack-python while
upstream of the latter switched its name to msgpack (without -python
suffix).  borgbackup devs are aware of this change and will fix it
eventually (if they haven't already), but what we can do right now is
add the following to borgbackup.SlackBuild somewhere before the line
that calls 'python3 setup.py install':

  sed -i 's/msgpack-python/msgpack/' setup.py
