[Slackbuilds-users] Installing scipy on -current

[Daniel Prosser]

Hey Judah,

I ran into this problem too recently. You can fix it by switching back 
to the old setuptools way of installing matplotlib; i.e., in the 
SlackBuild script, change the lines that start like this:

python3 -m build ...
python3 -m installer ...

to the following:

python3 setup.py build
python3 setup.py install --root=$PKG
