$Config{archname} is the architecture that copy of perl was built on, not necessarily what you're running on (similarly with $^O).
Ok... but if the perl binary being used has been built on those architectures can I not safely say that $^O is correct? At least of all the unix machines we have in our landscape the perl was built on and delivered on those architectures.
Update: I just answered my own question. No, I cannot.. hence
aix on both OS400 and AIX architectures. That just shows that the perl binary delivered with the PACE environment was built on an AIX architecture..

Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent. The slogan "press on" has solved and always will solve the problems of the human race.
