In fact, the only new-OS-version adjustment I can recall virtualenv needing to make is when Debian introduced dist-packages -- but even that doesn't really apply, as that was distro-packager change to Python itself. With a built-in virtualenv it would be the distro packagers responsibility to make sure their patch to Python doesn't break the virtualenv module.
FTR, there is some special casing for Mac OS framework installs included, too. Not sure if that should be considered a stability threatening issue though since Apple hasn't changed much on that layout, AFAIK.
Apple hasn't changed anything w.r.t. the basic layout of frameworks for a long time, but does mess with the structure of site-packages in their releases of Python. That shouldn't affect this feature though. For the most part a Python.framework is just a unix install stuffed inside framework. The special-case code in virtualenv for frameworks is needed because a framework uses another mechanism to look for sys.prefix than a classical unix install: sys.prefix is the directory that contains the python shared library. There is another feature of a framework install that would be nice to have in a virtualenv: the python and pythonw commands for a framework build are small programs that use execv to start the real interpreter that's stored in a Python.app inside the framework. This is needed to be able to access GUI functionality from the command-line as Apple's GUI frameworks assume they are used by code in an application bundle. Ronald
