The bleeding edge of Depend's sources are in my server's GIT repository. Depends is not under active development at the moment, as it is quite stable. If, however, you see any modifications that would have to be made, please send a patch relative to the GIT repository, if you can.
Alternative methods for getting the source is downloading them from SourceForge, where this project is hosted. I will publish an up-todate version of the sources any time there is a new one.
Remember to also download the documentation, unless you want to come back to this site to read it.
Previous releases of Depends can be found on the Developer's corner
