I don't feel strongly about it :-) To avoid the confusion with the
build-time binary ...

--with-runtime-perl ?

Don't understand that one. Who must set the variable ? 

If the packager, then it's awkward (obscure + must change the variable
each time a new target is built, effectively the same as Configure --with-perl)

If the user (preferred perl runtime), then either he can already do it
via PATH if the packager used '/usr/bin/env perl' or I don't see how it
would work (or it would require using hacks of the "eval 'exec $PERL if
$running_under_some_shell'" kind)
