You have good chances to get rid of it using the latest svn version of Rccp:

Thanks for the advice. Unfortunately, it doesn't work. I've downloaded and installed the latest version, made an Rcpp.package.skeleton("Foo", module=TRUE), and run R CMD CHECK Foo, resulting on a slightly different but still persistent warning:

** checking whether the name space can be loaded with stated dependencies ... WARNING
Error: .onLoad failed in loadNamespace() for 'Foo', details:
  call: value[[3L]](cond)

Probably some imports need to be declared in the NAMESPACE file.

However, the package works and I think a solution is not urgent.
