You might want to consider adding a Test::MinimumVersion test script
to the list of RELEASE_TESTING-only tests.
It's able to pick up this sort of thing before it gets to CPAN without
you needing to actually test it on the lower version.
It won't get everything, but it should find anything that is visually obvious.
If you want a standard one that you can just drop in, here's the one I
use for all my modules.
