It's probably better to fix the build system.

Failing that, I think it's more flexible and more supportable if you just wrap the build system with your own script that does whatever magic you are doing and have macports call your script in the build phase instead of trying to wrangle the macports machinery into doing what you're attempting.

(As a bonus, you don't have to implement your script in tcl if you don't want to).
