In a response to a comment of Gbacon's, you say that you want the answer to be platform neutral. I don't know of such a solution, but I wonder if it's even the right way to go.

If your goal is to find out on specific machines, I would use the tools that come with the platform. On Debian, that would include dpkg (pre-installed on any Debian system) or apt-file (not pre-installed necessarily) or other APT tools.

As an example, take a look at the output of this:

dpkg-query -L perl | less

You would obviously need to parse the output, but it strikes me as a start precisely because it is specific to the machine in question.
