All I can tell you is this:
on line 120 of boost/python/converter/arg_to_python.hpp, there's a
test for is_pointer_to_function<T>. That test is returning false when
it should be true for the given argument, which according to the error
message, is of type
The is_pointer test is succeeding, though, which is why we end up in
the ctor of pointer_deep_arg_to_python on line 215. If you can figure
out how to fix is_pointer_to_function for SunPro, it should start
