thanks; i'd missed that.  Any clue why, from my pov, they're so far behind?
5.8 seems ancient.

put it on the todo list; until then you can PERLV_PATH in your environment,
make distclean, and reconfigure.  in general, this should work for most
configure variables for any package's autoconf scripts.  sometimes you must
get kinkier and set the variable that autoconf uses, eg: ac_cv_path_PERLV_PATH
