| One way of solving it is to add the path to the
| R DLLs to the end of PATH.  For instance adding:
| 
| C:\Program Files\R\R-2.14.1\bin\i386
| 
| Once I've arranged those DLLs to be visible, the
| new problem is:
| 
| Fatal error: unable to open the base package

If I recall correctly I solved that by setting R_HOME as
your embedded R interpreter doesn't know its location...
