Do you mean in the case of dynamic linking? If so, that's awful. But
strange because I've seen many upstream projects release precompiled
binaries without that ever really being made into an issue. Or do you
mean in the case of static linking?

Hey, I'm all ears and open to alternatives. If you have a better
suggestion on how to get an application with said requisite runtimes to
run out of the box off optical media via XDG autostart without requiring
the novice user to have to do anything with their package manager, I'm
all ears.

This looks pretty complicated to get up and running and I wonder if not
just statically linking against libpng and libzziplib would not be
better? I'm also missing the elftools python dependency the script needs
and having trouble tracking down what I need to do to get that working,
assuming lddtree.py approach is the best way to handle this scenario.
