- fail hard in case if python is not built with selected extensions Currently it is possible to have python without zlib, despite the fact that zlib is stated as configure option. This leads to irritating behaviour of later components. - global build requirement checker - needs recipe - needs per profile dependency declaration - implement declared parts (*/buildout.cfg empty) - merge from: - https://svn.erp5.org/repos/public/experimental/erp5.buildout - https://svn.erp5.org/repos/public/experimental/erp5.buildout-zope-2.12/ - https://svn.erp5.org/repos/public/experimental/mysqlsenna.buildout/ - use more of buildout automatic dependency resolution - finalise openoffice-bin - do oood software and instance buildout
