That is a common perlbug, so you should perlbug it, many don't -- if enough people perlbug-it, maybe one of the perl5porters will take it upon himself to release an official dual-lived File::stat

In the meantime, you don't have to download a whole perl, you can just grab File/stat.pm from http://perl5.git.perl.org/perl.git/tree?f=lib/File

Might want to grab some .t also :)
