I suspect that you're missing the 32-bit libc and associated tools
(like the 32-bit runtime linker). You may also be missing the kernel
support needed to run 32-bit binaries, but that's less likely.
On Debian, there's a package called ia32-libs which contains or
depends on most of the basic libraries used by 90% of packages. I
don't know what the equivalent is on Centos, or whether you simply
have to install libc6.i386.
Alternatively, build the binary again on your 64 bit box.
