I might do it with a Task::Imager::PNG module that has Imager as a
prereq and has tests for png capabilities. Test failures would get
picked up by the harness.
To be most helpful to users, you should probably have the tests fail
with some sort of diagnostic message about how to install PNG support
for Imager.
