With my current issue with perl (p5-getopt-long and perl5.8), I spent some time looking into the tcl scripts used in macports.  It seems like a lot of the necessary functions are there to build a dependency graph/list.  I just have to learn tcl!

I did find that Eclipse has a tcl development environment, so I might be able to make some progress on this. :)

I've thought about integrating this into MacPorts base before. I
can't speak to how hard it would be. I can say that it would be hard
for me to do so. My tcl and my knowledge of MacPorts base is still
insufficient for the task. So I wrote it in PHP, which I know very well.
