Hallo!

Wenn ich ein Module habe, bei dem es je nach OS verschiedene Abhängigkeiten gibt, gibt CPAN:Test::Prereq immer Fehlermeldungen aus.
Kommt CPAN:Test::Prereq mit dem bedingten Laden nicht klar oder gibt es eine alternative Schreibweise für die Makefile.PL Datei mit der CPAN:Test::Prereq funktioniert?
