[Rd] couldn't find function "setClass"

[Jeff Gentry]

Hello ...

With a new checkout of R-devel (last update was 2003-09-11) we are having
a problem (it seems to be happening to all of us here on a few different
machines) where during install/check/etc when the 'save image' happens (in
packages using 'save image'):

** save image
Error: couldn't find function "setClass"
Execution halted


This is for all packages that are using classes.

Is anyone else having this problem?
