A brief status update on PEP 405 (built-in virtualenv) and the open issues:
1. As mentioned in the updated version of the language summit notes, Nick Coghlan has agreed to pronounce on the PEP.
2. Ned Deily discovered at the PyCon sprints that the current reference implementation does not work with an OS X framework build of Python. We're still working to discover the reason for that and determine possible fixes.
3. If anyone knows of a pair of packages in which both need to build compiled extensions, and the compilation of the second depends on header files from the first, that would be helpful to me in testing the other open issue (installation of header files). (I thought numpy and scipy might fit this bill, but I'm currently not able to install numpy at all under Python 3 using pysetup, easy_install, or pip.)
