Oh, that's a fun one. So setuptools/distutils/etc doesn't have the concept of a "configure" phase but it also doesn't remove the default implementation. The default implementation will try to do a 'make clean' first to remove existing build artifacts. Normally this does nothing with Python code as there's never a Makefile, but pillow has a Makefile. This makefile does 'python setup.py clean', which is running the *host* Python2 and you don't have distutils installed. So, it fails. Three solutions in order of hackiness (more to less) 1) Set CLEANBROKEN="1" in the recipe to stop the clean happening 2) Nullify do_configure in the recipe with do_configure[noexec] = "1" 3) Override do_configure in distutils3.bbclass to call setup.py directly to do a clean in do_configure I'd say do (1) in your recipe and I'll send a patch for (3) to oe-core. And yes, this recipe would be very welcome in meta-python.
