Installation issue: Qt 4 on macOS #12139
Description
I'm unable to build Qt 4 on macOS. Qt 5 built fine.
Steps to reproduce the issue
$ spack install qt@:4 platform=darwin
...

@davydden you helped me last time I had problems building Qt on macOS. Any thoughts?
EDIT: Also note that if you run Spack with Python 3, you'll need #12138 to get qt to work. These error logs were produced using the current package and Python 2.
