Well, what we were specifically discussing in that message is not quite
aimed at your problem.
Now that we've discussed it a bit, I think the following may be adequate to
solve it:

1. Make sure a declaration of class_wrapper<T> is visible wherever you are
wrapping a function which returns T or accepts T as a parameter. One way to
do this is by declaring a subclass which you don't neccessarily use:

struct Xclass : boost::python::class_wrapper<X> { Xclass(); };

2. Dynamically link your interdependent modules to one another.

If there is a better approach, I hope we'll discover it during our
exploration.
