[Rd] Suggests and examples

I apologize in advance for probably missing something obvious, but if someone could point me in the right direction I'd be grateful. This NOTE is not unique to our package (I list a few others, below).

Package bcp has several Suggests (strucchange, for example).

Then in an Rd file, we have

if (require(strucchange)) {

  # Doing some examples making use of strucchange


The CRAN check results reports the following NOTE:

checking for unstated dependencies in examples ... NOTE 'library' or 'require' calls not declared from: DNAcopy coda strucchange

I note the same problems in other packages (e1071, Deducer, diveMOVE, gplots, ...)

Any hints? I'm pretty confident that Suggests: is preferable to Depends: in such a case, but I can't seem to address this note. Thanks,
