The only way is to have exactly the same runtime environment (i.e.,
having installed the same distributions with the same version on the
same architecture). Otherwise you have to recompile.

Well, in a cluster you might be able to configure your systems
sufficiently homogenous that it works.

No, only once when they install it on their machine.

No, there is no way to avoid that. Say hello to the realities of
software distribution :-).
