Subject: | File::Spec not 'use'd |
In your new Makefile.PL you use File::Spec's methods.
New EU::MM 'use' F::S by default, hence why your Makefile.PL works
on 5.8+. It also works on earlier versions that have had EU::MM upgraded.
However a 'fresh' 5.6.1 (for example) doesn't have such a EU::MM so
an error pops up saying that you've not 'use'd File::Spec.
cheers,
