It would be nice if R used its shared library itself, as it does on 
Windows.  However,

- on some platforms we cannot build the shared library at all (since some 
of the crucial system routines, usually the Fortran run time, are not 
PIC, or BLAS and other libraries are not shared).

- on some platforms there is an appreciable performance hit (I have seen 
reports of 5-10%).

We don't have the resources to build and check different versions of R for 
different platforms.
