I think what you're going for here is similar to the
package-propagated-input-refs procedure that was added to (gnu packages
version-control) recently.

A patch I sent to the list earlier would move that procedure to (guix
packages) so that it could be used elsewhere.  It seems to be something
that many other perl-using applications need (e.g. gnucash, clusterssh).
