Here is how I generally do this:
1) Download and extract the source.
tar zxf R-2.14.2.tar.gz
2) Compile the 1st instance.
~/src/R-2.14.2/configure # no need to specify --prefix here
make -j2 # use -j4 if you are on a quad core
3) Run the first instance.
If you want more than one instance, do 2) and 3) again
for each additional instance (replace R-2.14.2-instance1 by
Never do make install!
I must have done this 100 times since I started to work with R,

everything goes under R-2.14.2-instanceX/library/).
