And the issue of reliance on external libraries isn't confined just to
linux. You can't, for example, build an OSX standalone and expect it
to run under Windows. There are always going to be OS dependencies.
This issue that Bob ran into here is that you can't build a standalone
that relies on gnome GUI libraries and expect it to run in a kde
environment where those libraries don't exist. If I build a kde
standalone that used some specific features of my desktop environment
I'd expect that it wouldn't run on Bob's gnome desktop either.

A standalone could, for example, have a dozen QuickTime movies as
external files. It's not necessarily just a single file. As I see it,
the distinction between a stack and the standalone built from that
stack is that in the IDE the stack relies on resources from the IDE
(the rev engine, various libraries...) which are which are packaged
together into the standalone when it's built. So you end up with as
much of the IDE as you need without the actual IDE.

(MSWord's spelling checker didn't like "MacOS", and suggested that you
might have meant "maces"... of course, my email client didn't like
"MSWord's" and suggested "swords"...)
