checkout-daq-package.py -p is not working

[ron003]

Seems:
-def checkout_commit(repo, commit, outdir, is_success_required):
+def checkout_commit(repo, commit, outdir, is_success_required = True):
may be needed.
I'll submit PR shortly.

Thanks for the PR. However, it seems like using checkout-daq-package.py to check out a single package and not doing a version crosscheck (the arguments needed to reproduce the error) remains broken and there are deeper issues there to be fixed (e.g., the commit has the Python None value, breaking the result). I'll take a look when I get a chance.
