Hmm.  file says it is dynamic, ldd says it isn't.  ldd works by
executing the program, so something preventing execution might cause
it to give a misleading error.  Plus, ldd run on a static executable
on my system outputs "statically linked."

Do you have CONFIG_IA32_EMULATION enabled in your kernel?  (zcat
/proc/config.gz | grep CONFIG_IA32_EMULATION should tell you -
assuming your kernel enables /proc/config.gz).

Also - do you have a /lib/ld-linux.so of some sort on your system
(might be in /lib32, or wherever your distro sticks 32-bit libraries)?
 Mine is /lib32/ld-2.17.so.  If you're missing that you won't be
running anything 32-bit, and you need to install whatever package
provides it.  It is entirely possible that 32-bit support is not
installed by default in your distro - little requires it these days.
I could see them including it in the kernel but not installing the
linker, since the latter is just a few files that need to be
installed.

If you're missing the linker the kernel returns the same error as a
file-not-found, so that tends to lead to misleading error messages.
