--skip-alias is not supported in all versions of which. While here, explicitly import CalledProcessError - some versions of Python didn't seem to mind, but it's not true for all versions. Also print related error messages to stderr instead of stdout - this helps with debugging since in some tests the stdout is redirected to a file.
