Bugs Fixed:

`67737 <https://launchpad.net/products/zc.buildout/+bug/67737>`_
     Verbose and quite output options caused errors when the 
     develop buildout option was used to create develop eggs.

`67871 <https://launchpad.net/products/zc.buildout/+bug/67871>`_
     Installation failed if the source was a (local) unzipped
     egg.

`67873 <https://launchpad.net/products/zc.buildout/+bug/67873>`_
     There was an error in producing an error message when part names
     passed to the install command weren't included in the
     configuration.
