Ok ... it would've be useful to haven known which distro you're using.
/usr/bin/cp is 32-bit on OpenSolaris 2008.11 ...
# file /usr/bin/cp
/usr/bin/cp: ELF 32-bit LSB executable 80386 Version 1 [FPU],
dynamically linked, not stripped, no debugging information available
#
An interesting aside ... /usr/bin/{cp,mv,ln} are all linked to the same
file (i.e. one programme for three commands) ...
# ls -li /usr/bin/{cp,mv,ln}
14563 -r-xr-xr-x 3 root bin 40732 2008-11-20 07:43 /usr/bin/cp
14563 -r-xr-xr-x 3 root bin 40732 2008-11-20 07:43 /usr/bin/ln

It's the mv that makes it work. The symlink dance is unnecessary

On my distro the /usr/lib symlinks just point back to /lib
The symlinks get traced back to the file, and the mv makes the switch of
the file atomic.
crle isn't active on my system ...
# crle
Default configuration file (/var/ld/ld.config) not found
Platform: 32-bit LSB 80386
Default Library Path (ELF): /lib:/usr/lib (system default)
