We run R in a multiuser environment (Mac OSx Leopard Server

multiple versions of R (R-2.7.2 and higher) available on the same
machine. I have successfully installed multiple R versions using
the binaries for Mac OSX and deleting the relevant Receipt before
installing the newer version of R. My problem occurs when allowing
individuals to run different versions of R. I would like to be able
to allow users to run any verison that is currently installed. The
Rswitch gui works nicely if I want to make a global switch (for all
individuals) from one version of R to another. The Mac OSx FAQ
recommends not to hardcode the shell scripts to start R to a
specific version (FAQ 12.15). Am I better off building R from source
for each version we need and bypassing the Frameworks approach for R
used by the binaries or is the a "safe" approach to use the binaries
and utilize hardcoded shell scripts to point to a given version of
R? (I have created some shell scripts (hacked from those provided)
that allows me to start either R-2.6.1 or R-2.7.2 but the Mac OSX R
FAQ recommends against this approach.)
The FAQ clearly describes the issues so you're free to use it if those
don't apply to your setup or they are not critical to you. The whole
point of the FAQ entry is so you can make an informed decision about
whether it's ok for you to use it that way or not.

If there is somewhere else I should be reading, I would appreciate a
pointer and I would be happy to review.
Thanks for any help.
