In Lenny/Sid, all Vim packages except vim-tiny and vim contain the
python support, so it is more likely that a user will have a vim binary
that can be scripted via Python.
On the other hand, in Lenny/Sid the path that plugins used to be
installed to (/usr/share/vim/addons) is no longer automatically included
in Vim's runtimepath. This means that manual work is required to enable
the plugin.

See above explanation.
Also, taking a look at the current bicyclerepair package, the addon is
now installed to /usr/share/addons/vim/ftplugin/python_bike.vim. This
means that the functionality will only be used when editing python files
(once the user has enabled the plugin) instead of when editing any file,
as was the case when it was installed to plugins/bike.vim.

Python, by default, has '' as the initial item in its sys.path list
$ python
Python 2.5.2 (r252:60911, Jun 25 2008, 17:58:32)
[GCC 4.3.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages/Numeric',
'/usr/lib/python2.5/site-packages/gst-0.10',
'/var/lib/python-support/python2.5',
'/var/lib/python-support/python2.5/gtk-2.0']
This means that anything in the current directory is first priority when
trying to use/import a module.
/usr/lib/pythonX.Y/compiler/transformer.py has the following lines that
are run when the module is imported
import token
...
_cmp_types = {
token.LESS : '<',
token.GREATER : '>',
token.EQEQUAL : '==',
token.EQUAL : '==',
token.LESSEQUAL : '<=',
token.GREATEREQUAL : '>=',
token.NOTEQUAL : '!=',
}
When the bike Vim plugin is loaded, it imports the bike python module,
which imports compiler (and therefore compiler.transformer). Since
Vim's current working directory is roundup-X.Y/roundup, the above lines
from transformer.py combined with '' being the first item in sys.path
cause python to load the token module in the current working directory
(from roundup's source) instead of using /usr/lib/pythonX.Y/token.py.
