Thanks for doing that :-) I looked in to the dependencies you discovered, and ... > In no particular order, the following invocations occur in those contents > > /usr/bin/python We already depend on this one. > /bin/sh <---hmm, in Ubuntu, this is a symbolic link to /bin/dash /bin/sh is provided by dash, which is marked Essential, which means we don't need to depend on it.

On Precise and Lucid this is provided by sysvinit-utils, which is not marked Essential. However if I build a deb that depends on it, lintian complains that I depended on an Essential package. I think this means there is some package marked Essential which depends (perhaps indirectly) on sysinit-utils. If that's true, then we should *not* depend on sysvinit-utils.
