davido, that is exactly the approach I took with Module::Cooker. I left out any minimum perl version and waited for FAILS to come in. The only one was on 5.6 so far and seems tied specifically to File::Path. make_path seems to have been introduced in F::P v2.06_2 so I am setting that in a prereq in Makefile.PL and going to see what happens from there.
The only real annoyance is that in order to test on a given version I have to have a clean perlbrew install, and that can be problematic at times on a shared hosting server.
It helps to remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.
