This is really because these packages are using the "traditional" GNU 
Objective-C runtime API
(eg, class_get_super_class()) and have not been updated to support runtimes that
use the "modern" GNU Objective-C runtime API (eg, class_getSuperClass()).

(I'm calling them "traditional" and "modern" because that's how the GCC manual 
calls them,
see 
http://gcc.gnu.org/onlinedocs/gcc-4.6.0/gcc/GNU-Objective_002dC-runtime-API.html).

We really should update everything to support the new API. :-)

Thanks
