Hi,
Python Policy 3.2 states:
3.2 Programs Using a Particular Python Version
"""A program which requires a specific version of Python must begin with
#!/usr/bin/pythonX.Y (or #!/usr/bin/env pythonX.Y). It must also
specify a dependency on pythonX.Y and on any pythonX.Y-foo package
providing necessary modules. It should not depend on any python-foo
package, unless it requires a specific version of the package (since
virtual packages cannot be versioned). If this is the case, it should
depend on both the virtual package and the main package (e.g. Depends:
python2.4-foo, python-foo (>= 1.0))."""
Consider gnome-osd which depended on python2.4-pyorbit-omg before
pyorbit was transitioned. Now pyorbit only ships python-pyorbit-omg
which Provides python2.4-pyorbit-omg, but users with gnome-osd
installed -- and hence python2.4-pyorbit-omg as a real package
installed -- won't get python-pyorbit-omg.
Shouldn't such packages Depend on "python-pyorbit-omg,
python2.4-pyorbit-omg", even if they don't need a particular version of
python-pyorbit-omg (contrarily to what 3.2 §2 requests)?
