Make sure it's a 32-bit ELF executable and not 64-bit ELF:

	file ./less

You cannot run 64-bit binaries on a 32-bit machine.

If that checks out, then try ldd to make sure all the libraries can be
found and ktrace to find out where it's dying.

If it dies inside one execve then try using objdump on it to dump the ELF
headers.
