Fixed (if I understand bakefile correctly), I'm recompiling it now and
so far so good.

Can you not do this at all, because it is in a library? I thought this
would be a clever trick to ensure that all the bindings were
initialized and made available at runtime. This way you do not have to
know the name of anything and so we can even remove the dependence on
the wxWidgets binding.

What would be an alternative? One way would be to make the user add
any bindings they want to a static member of wxLuaBinding themselves
in the wxApp::OnInit. The only reason to have the static member is so
that they don't have to always add the bindings everytime they create
a new wxLuaState, but by default it will try to load the ones set to
the static wxList of them.

I thought they are "run" in the order that they're linked. Or in the
cases of some compilers, the reverse order that they appear on the
linking command line.

Hopefully.
