[Rd] NAMESPACE problems

Hi.

I am having difficulty following section 1.6.6 of the R-extensions manual.

I am trying to update the Brobdingnag package to include a NAMESPACE file (the
untb package requires the Brobdingnag package).

Without the NAMESPACE file, the package passes R CMD check cleanly.

However, if I include a NAMESPACE file, even an empty one, R CMD check
gives the following error in 00install.out:



wt118:~/packages% cat Brobdingnag.Rcheck/00install.out
* installing *source* package ?Brobdingnag? ...

ERROR: lazy loading failed for package ?Brobdingnag?
* removing ?/Users/rksh/packages/Brobdingnag.Rcheck/Brobdingnag?

AFAICS, all the setGeneric() calls are pretty much like this:

setGeneric("getX",function(x){standardGeneric("getX")})



Can anyone advise?


thank you

Robin
