I have actually decided to move away from the one-big-executable concept.
I had never packaged my application within the tclkit (don't want that),
and now I am abandoning the tclkit entirely.
It's one less dependency for me to worry about.
I have now repackaged my application with bundled tcl/ folders, and the
executables (linux 32/64, mac os x, windows 32/64) are built so that
they can be run from any installation location.
I require 'wish' on mac os x, both 'wish' and 'tclsh' on windows,
and want 'tclsh' on all platforms.
