The problem is apparently your Ubuntu 7.2 64bit does not have
32 bit support libs installed, so trying to run 32bit binaries on the
64bit OS without them gives that error.
To fix the problem, install Ubuntu's optional 32bit support:
# apt-get install ia32-libs ia32-libs-gtk ia32-libs-kde
My guess is only the "ia32-libs" package is needed for Rush to work,
since it makes no use of gtk or kde. But apps like shake might need this,
so it couldn't hurt. YMMV.

Too bad the linux kernel is reporting the error as 'Command not found'.
Very misleading.
Would be nice if it report something useful like 'Exec format error' (ENOEXEC),
or 'executable format not supported', or some such.
I should add the kernel didn't log any useful comments to /var/log/messages,
/var/log/secure, or in demsg or to /dev/console. Which is kinda a surprise.
I would think someone trying to run binaries not supported by the OS
should show up on the admin's radar.
