Well, that is what I tried (both), however it would not work for me. So I assumed this the story was somewhat more complicated and was wondering, what's the trick behind.

The program I am working with has a non standard configuration step. I am trying to figure out how to do this right and for convenience I work directly with the macports work directory. In general, I would just use `sudo`, not caring about the fact to operate as root. Unfortunately the script is preventing to be run as root (see above), so I was trying to do so as macports and failed to change user ...

Any ideas?
