Looks like it works.

Everything in its right place. However, according to
http://www.openwall.com/phpass/ smart people in phpBB3 team changed
$P$ to $H$ without changing meaning, so you need to oversmart them.
Put the following line right before line 154 (return Authen...):

$hash =~ s/^\$H\$/$P$/;

That will replace $H$ in the beginning with $P$ and Authen::Passphrase
should find proper module.

Best regards, Ruslan.
