I don't get your error here. The only thing that's wrong in your tgz is
that you link the client against libaes256.a, but your lib is called

That's how it should look like. The error tells you that the hiworld
binary is missing or has inappropriate rights. (Btw.: You're still
building as root...)

You might want to have a look at the scripts in l4/tool/runux - there is
also a config file template which you can adapt for your system. Then
you don't always need to copy around your binaries.
