Comment (by afb at macports.org):

 Hmm, port lint only does a two-pass static analysis at the moment (once to
 check the file, like for encoding and location and once to parse the file
 syntax and read the basic metadata variables)

 Things like deprecated tcl commands should be evident from the trial build
 of the port, so I'm not sure whether they need to be checked with lint ?
 (since that would mean having to parse/run stuff)
