Happens from time to time, in particular if compiled code is included.

Now I'm completely lost. if you really want to keep separate libraries 
for R-2.x.y and R-1.x.y, you can simply call R with R_LIBS set, or for 
your convenience write a two line shell script that sets R_LIBS 
appropriately and calls the relevant version of R after that.
