This is not necessary.
If R is installed into /usr/local/R-2.10.1, set the environment variable 
CMAKE_PREFIX_PATH accordingly:
$ export CMAKE_PREFIX_PATH=/usr/local/R-2.10.1:$CMAKE_PREFIX_PATH

If the FindR.cmake is more or less ok, it should then find R there.

Please don't do that.
Instead try to fix the existing FindR.cmake and post the patch here (diff -bup 
FindR.cmake.original FindR.cmake)
