I'm surprised I didn't get the "perhaps you forgot to load ..." message that usually comes with this sort of error.
Odd, I get the message...
>perl -e "bless({}, 'Cow')->moo();"
Can't locate object method "moo" via package "Cow" (perhaps you forgot
+ to load "Cow"?) at -e line 1.
>perl -e "STDOUT->print();"
Can't locate object method "print" via package "IO::Handle" (perhaps y
+ou forgot to load "IO::Handle"?) at -e line 1.
>perl -v
