R does that by setting LD_LIBRARY_PATH in its front end script `R',
so it should not be necessary to use -R. I don't need it ....
One possible source of confusion: in R-devel (and 1.5.0-to-be) the
variable LIBS has been replaced by LDFLAGS, so there you would use
./configure -C CPPFLAGS=-I/$HOME/include LDFLAGS=-L$HOME/lib
(and you should set the variables this way as they are now `precious'
and will be re-used if re-configuration is needed).
