Hmmm. You have to INSTALL a package. Shared libraries will be build on 
the fly while installing. Hence I think you have not read the mnauals 
carefully enough.

You can put C and Fortran files in ./src, the shared library will be 
installed during
   R CMD INSTALL pack
into the ./lib directory.

You really want to pass a directory and a filename to your shared 
library? So, why are you using R in between?
