dependencies, version control and keeping up to date

OS: Windows XP Pro

G'day everyone,

Over the last two years I've written software for my employer in a
wide variety of languages including Ada, Assembler, BASIC, C, Delphi,
Fortran, FoxPro and Perl. Quite a few of these projects depend on the
work of other developers who from time to time update their libraries.
What I need is some way of detecting those changes in a semi-automatic
way, such that the situation is flagged, the software downloaded, the
package rebuilt (or me flagged to rebuild it manually), and the
resulting binary to be posted somewhere.

Limiting the discussion to Perl, I've found that there are various
methods of extracting module names from a piece of perl code (using
perl -d:Modlist=cpan,nocore), and one can get cpan.pm to output what's
been changed with respect to its database v/v the local mirror (cpan -
O). What I would like to know, before I reinvent the toasted cheese
sandwich, is whether anyone has developed anything which takes these
two pieces to make a whole dependency control tool.

Kind regards,
