[Rd] R CMD check ignores .Rbuildignore?

[Ross Boylan]

The contents of .Rbuildignore seems to affect
R CMD build
but not 
R CMD check.

I'm using R 2.4.0 on Debian.

Is my understanding correct?  And is there anything I can do about it?
In my case, some of the excluded files contain references to other
libraries, so linking fails under R CMD check.  I realize I could add
the library to the build (with Makevars, I guess), but I do not want
to introduce the dependency.

Thanks.
Ross
