Put "my_default_dir.pth" in each of your virtual environments
(preferably via a symlink if you aren't on Windows). If you want to mix
two environments together, put both of their .pth files in a single
directory (again via symlink if you can).

A collection of .pth files in a directory is easy to manage. Messing
with environment variables is a PITA - you need an external solution to
keep track of what the environment variable should contain for each
