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)
  error: failed to load module yada from package Foo
could not find function "getClass"
Execution halted
A namespace must be able to be loaded with just the base namespace
loaded: otherwise if the namespace gets loaded by a saved object, the
session will be unable to start.
Probably some imports need to be declared in the NAMESPACE file.

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