Try to read FAQ on CRAN. It is explained there as well as in V&R 'S
It is not enough to copy the library file. You have to install it. On
linux, you simply type (on OS prompt),
$ R CMD INSTALL /path/to/pkg_version.tar.gz
I think, it is similar in OS X. Basically, it compiles the package for you.
There are also pre-compiled recommended packages for OS X on CRAN.
