Same thing on my ubuntu.
What I understand from this is that Koen is referring to 64bit binary 
files located in noarch_base_libdir, that is /lib. Please correct me if 
I'm wrong.
Another thing I bumped into... is there any reason why udevd ends up in 
/lib (/lib64) and not in /sbin? On my machine is located in /sbin and 
I'm assuming it is the same for most distributions.
