As toolic stated, older versions of keys() forced you to hand it a hash (not a hash reference).

To fix this, simply dereference your hash:

my @gotHashRefKeys = keys %$hashRefOutput;

or, if you prefer

my @gotHashRefKeys = keys %{ $hashRefOutput };

[download]

As you are finding, CPAN testers is fantastic for checking that your code is backward compatible.

A note from perldoc -f keys (as of 5.18.0):

This aspect of "keys" is considered highly experimental. The exact behaviour may change in a future version of Perl.

So probably best to pass in the dereferenced hash ref, or in the future you may find the tests breaking pre-5.14.0 and post any changes to keys().
