Thanks, that does help a bit, but where we noticed it doesn't work is if the ImportTest module imports modules that are nested deeper within site-packages, which is the case for our production code. (There is the requisite __init__.py in each of the module directories.) I guess what I find most puzzling is why everything works as expected on the Ubuntu system and there's this difficulty on the CentOS system; seems that the vital parts of the configuration are compatible. Thanks again.
