I am using a standard perl install on Ubunutu 9.10, perl version is 5.10.0. So including MIN_PERL_VERSION won't achieve what I want on those versions where I need it in the first place :)

It seems I have to use "use <version>" to make this work. However I could include the MIN_PERL_VERSION in addition and not worry about the warning that appears for the parameter in earlier versions of ExtUtils::MakeMaker.
