Before we used `easy_install` command to handle installation in one shot, now this is split into two phases: - buildPhase: python setup.py build - installPhase: python setup.py install Each of those commands have the ability to pass extra parameters through buildPythonPackage parameters as `setupPyInstallFlags` and `setupPyBuildFlags`. Phases now correctly execute post/pre hooks. In configurePhase we inject setuptools dependency before distutils is imported to apply monkeypatching by setuptools that is needed for special features to apply. We don't have to reorder default phases anymore, as test phase comes after build and that works. I rewrote offineDistutils into distutils-cfg with a bit cleaner syntax and ability to specify extraCfg to the config file. Plone packages are failing and garbas said he will adopt them to the new functions. The rest of the packages I fixed and these commits shouldn't break any package (according to my testings) and they introduce 16 new jobs and fix 38 that were broken before.
