--- Comment #5 from Tom "spot" Callaway tcallawa@redhat.com --- (In reply to Dave Olsthoorn from comment #4)
Maybe the confusion is because of this: https://metacpan.org/changes/distribution/DBIx-Simple#L26
It seems the versions after 1.32 are not released into the public domain anymore, but released under "any(OSI)" (as the change log indicates).
Looks like you're right. From 1.32:
=head1 LICENSE
There is no license. This software was released into the public domain. Do with it what you want, but on your own risk. The author disclaims any responsibility.

However, since the author has reasserted copyright post 1.32, that doesn't change my advice in comment 3.
