Two quick comments while I catch up with the email back log from travelling:

It's 'r-base-core-ra' and I mentioned that in off-line email only to show
that you can arrange to have more than one R interpreter in Debian.

As Duncan, Uwe, and I have told you already, this may get frustrating in the
long run as changes may break your bindings. Accessing a hidden API is doing
so against the wishes of the API designers / maintainers...

You do not need a chroot or second computer either. Just how r-base-core-ra
uses the normal --prefix argument to configure to install into a second,
non-overlapping file tree, you could use /usr/lib/ROcaml/ or some directory
other than /usr/lib/R + /usr/share/R which are taken by the R package for
Debian. R developers use the same --prefix trick to keep r-releases,
r-patched, r-devel, ... installed at the same time.
Anyway, good luck with the endeavour. Something useful may well come from it.
Cheers, Dirk
