    <<-EOS
PySide Python modules have been linked to:
    #{HOMEBREW_PREFIX}/#{site_package_dir}

Make sure this folder is on your PYTHONPATH. For PySide development tools,
install the `pyside-tools` formula.

Ensure PySideConfig.cmake gets generated with a default value for
SHIBOKEN_PYTHON_SUFFIX, otherwise an infinite loop will occur.
