Only if someone messed with Python's default build structure. The
Python stdlib should contain an .egg-info file marking the presence
of wsgiref 0.1.2. Some Linux distributions may remove this file due
to a misunderstanding of its nature/purpose.
Note that this is specific to wsgiref, and doesn't apply to any other
separately-distributed packages bundled with 2.5, such as sqlite or
ctypes. For these, you'll need to do version checking as described below.

requires = [...]
if sys.version < "2.5":
install_requires = requires
