Would you really need them - a scripting language should work the
same regardless of how the interpreter was built, which, I think
is the logic behind not having 32bit versions in the first place?
We haven't actually done any 64bit nodes at Oxford (since our first
64bit grid hardware doesn't arrive until tommorrow), but the current
plan is to install a pure 32bit SL4, then move on to test running that
with the 64bit kernel but an all 32bit userspace. That should work,
and should provide us the best of both worlds; all the compatibility,
and non-PAE memory addressing.
