Success!

With these 2 fixes, it now builds using clang (with GNU libstdc++):

     -- Set runtime path of 
"/home/oberstet/pypy-5.6-linux_x86_64-portable/site-packages/cppyy_backend/lib/libcppyy_backend.so" 
to ""
     install finished
done
   Removing source in /tmp/pip-YrtrlD-build
Successfully installed PyPy-cppyy-backend-6.6.9.0
Cleaning up...
oberstet at thinkpad-t430s:~/scm/oberstet/scratchbox/cpp/capnproto/test1/PyPy-cppyy-backend-6.6.9.0$

However, the basic example spills out weird things:

oberstet at thinkpad-t430s:~/scm/oberstet/scratchbox/cpp/capnproto/test1$ 
pypy MyClass.py
unknown type code: P

unknown type code: �

Code is all here:

Example was built like this:
