I would suggest creating an empty subclass then: 
package Test::It;
our @ISA = qw(Package::Under::Test Utility::Subs);

1;

# ... later, in another file
my $under_test = Test::It->new(...);

This way any method is first searched in the Package::Under::Test's hierarchy and only then in Utility::Subs.
