teapot-client uses [lsort -dictionary] to determine the newest package
version, which is incorrect (case in point: tdbc).

The following patch fixes this AND inclides a workaround for vectcl
http://teapot.rkeene.org/entity/name/vectcl/index.html which doesn't
conform to [package vcompare].  The latter should surely be fixed:  ActiveState's teapot knows it only as "0.1".
