Generally speaking, it is not a good idea to use a library built
with a more recent environment (Operating System, runtime, ...)
on a system with an older environment.

If wish to  avoid "Irix-n.m versions of my application", do
your compile on 6.3. You should have no problem running an application
built on 6.3 on 6.5.
