This package has an Initialize method that uses dyn.load to load a dll that was built separately, and then uses .C() to make calls on the functions in that dll. This worked fine in 2.15, however, I see that now for 3.0 .C() will only search in the namespace of your current package. This seems to make it impossible to use dyn.load for loading a dll, as I can't find a way to get the loaded dll to belong to the namespace of the package that is using it. It tells me that the function I'm trying to call is not resolved from the current namespace, or if pass the .C function a value for the PACKAGE optional argument it tells me that the symbol is not available for .C() for the package.

If you need an example for such an ugly hack, see how we did it in the 
BRugs package.

Best,
