Ever wondered about Perl modules that would help you build a dependency tree in a manner similar to make? A recent PerlMonks question was also curious. Only one answer (so far) but the question plus the answer have some interesting ideas.

The answer suggested cons. cons is a very old system and I had not realized it was still active...and based on the e-mail archive, it isn't. The FAQ was last updated in 2001. This would not likely be the first place I would look.

The question itself mentioned two modules that I was unaware of: Algorithm::Dependency and Decision::Depends. The former appears to be the module with the most recent update, but the OP seems to have chosen the latter to help him solve his problem.
