Just a thought: If you need to distribute a script that is supposed to
run on different systems, and that contitutes its own "software package"
(is an executable, has a manual and possibly some related documentation
and examlpes etc.) then you also have the option of using things like
GNU auto-tool (autoconf+automake) to generate a portable "configure"
script that can be used for setting up the system-dependent parts of
the script (or you could roll your own installation script).  That way,
portability options (and dependencies) are handled once and for all when
installing the thing.

A script meant for wider consumption than by yourself is like any other
software.
