[R] smoothScatter() and the KernSmooth package

I am getting the following error when running a package check
  Error in loadNamespace(name) : there is no package called 'KernSmooth'
  Calls: <Anonymous> ... loadNamespace -> withRestarts ->
withOneRestart -> doWithOneRestart
  Execution halted

The error happens in a function which calls graphics::smoothScatter

I found this e-mail on the r-devel list where this problem is also reported.

So I could add KernSmooth to Suggest in the DESCRIPTION but I have a
few questions:
(and I am citing from the e-mail above to which I could not find a reply):

"I have a few questions: isn't it unusual the way smoothScatter calls

grDevices:::.smoothScatterCalcDensity() and KernSmooth::bkde2D(),
i.e., without requiring the packages?
Shouldn't "graphics" suggest "KernSmooth"?

best regards
