For this one, you have to upgrade further and check out the unstable branch
(git 'master' branch, see http://pari.math.u-bordeaux.fr/git.html, you can
directly download a snapshot from that page if you're unfamiliar with git).

In that version 2.8.*, the old pair zetakinit / zetak is gone, but you can now
use lfuninit / lfun (or directly lfun for that matter) for much more general
L-functions. The implementation is faster and more robust as well.

   realprecision = 308 significant digits (300 digits displayed)
(09:29) gp > lfun(y^2+3, 3)

See ??Ldata, ??lfuninit, ??lfun and/or my tutorial from January's Atelier :
