The ns executable should be self-contained (including all the internal
tcl code needed to run a simulation).  You should be able to build ns,
save the executable, and throw away the rest.

If you're using shared libraries, you'll need to be careful to keep
the right versions around (ldd will tell you what you need).

Note that the ns executable doesn't include "all" of ns.  External
pieces like the scenario generator, gt-itm, the validation programs,
etc. are separate.
