No, they shouldn't:

* Linux runs on a lot of architectures, e.g. executables
  compiled for i386 won't run on PPC.

* Unless compiled statically, executables and libraries depend
  on other libraries. If these libraries aren't installed, or
  installed with a different version, you might run into
  trouble.

I guess, you're running into dependency problems.

BTW, please use the latest version of a tool when reporting
bugs. You're using either RubyScript2Exe 0.5.0 or 0.5.1, while
the latest is 0.5.2. (BTW, updating to 0.5.2 won't solve your
problems... :})
