R devel - Sep 2004 - Proper way to export S3 method when base is not in a namespace

What is the proper method of exporting an S3 method from a package with a
NAMESPACE when the base method is from a package which does not have a
namespace?

EG,  The Design library defines 'contrast', 'contrast.ols', .. 
and I've
written 'contrast.lm' which I want to include in a private package.   If
I
put

	S3method(contrast, lm)

in the NAMESPACE file, R CMD check fails with

Error in .tryQuietly({ : Error in library(package, lib.loc = lib.loc,
character.only = TRUE, verbose = FALSE) : 
	package/namespace load failed
Execution halted

For the moment, I've simply put contrast.lm in the exports, but I would like
to know what the proper procedure is.
