Ok, I might as well comment on my changes ie your problem

empty return, instead of last, in dependency_checks, made @all_pronoun_matches empty

After that, @all_pronoun_matches wasn't all empty, but still had some empty arrayrefs, which is why I added 

 and @$matches);
 and @$pronoun_matches);

This should have been a change in dependency_checks to return undef instead of an empty ref, but, well, oh well :)

Next I took a look at \%counts, \%pronouncounts and noticed %counts also contained \%pronouncounts -- and the same went for \@all_matches, it also contained \@all_pronoun_matches, so I went back and modified sub dependency_checks and added not $foundPronouns

That got the program 98% there, except there was a missing count number, naturally, since counts no longer contained pronouncounts, so I changed $header, and we're 99% there, the only thing misssing is an extra newline before header :)

Hopefully it makes sense :)
