That's a design problem of BeOS than. Under Unix, there is no
reason why a shell scripts is inferior to a normal program.

So what? This could be attached the startup script as well.

Again, how does this affect UNIX? It's an OS specific calling
mechanism, find an OS specific way to solve it.

THAT'S NOT THE PROBLEM. The problem is storing a _relative_ rpath
in the executable, which can create a lot of *very* nasty problems.
Google a bit, e.g. for the -L handling of SunOS and AIX (IIRC).

This is not supposed to help each small program on the system,
but big "packages" like a Tomcat server or a web browser.
