some Python packages fail to build. One such example is

Hi, this happens because we cross-compile the arch:all package (which 
we shoudn't) and also bitbake dependencies are not propagated 
correctly. Fixing all that has been taken care of in the following 
patches: 

- handle DPKG_ARCH=all case for transitive deps 
- dpkg-raw: add files to source package 

These are not yet applied (but hopefully they will be soon).

   Many thanks,
