I thinkLennart is saying that on a 64 bit system they would have to go
to /usr/lib32
But this is wasteful, it means that:
A) You cannot use the same packages on a 32bit system and a 64bit
system. You have to compile additional 32bit packages for installation
on 64bit systems, or do some fancy relocation within rpm.
B) you cannot easily convert a system from 32 -> 64 bit as you would
have to move everything around.
Simo.
