The install script is fine -- it's what I always use.

That's correct -- print without linearize values, measure, and the put
the values into curve.

The .quad files are the actual curves.  They are just a big table of
numbers.  Use TextEdit if
you really want to see what's there.  Better is the new program called
QTR-CurveView.
Drop a bunch of .quad files onto it and it shows nice graphs of the inks.
