It's not so much that the tasks are related but rather that rev-upgrade is already testing all the links so it seems like an efficient place to test the license of files port. See below for what appears to be a case where no files are actually linked but the port still shows a license conflict.

Yes, I currently use port_binary_distributable.tcl.

This is what I am trying to understand.

$ /opt/local/var/macports/sources/svn.macports.org/trunk/base/portmgr/jobs/port_binary_distributable.tcl -v pdf2djvu
dependency 'ImageMagick' has license 'Apache-2' which conflicts with license 'GPL-2' from 'pdf2djvu'
$ port deps pdf2djvu
Full Name: pdf2djvu @0.7.13_0
Build Dependencies:   pkgconfig, gsed
Library Dependencies: djvulibre, poppler, libiconv, GraphicsMagick

So far no dependency on ImageMagick so it must be an rdep.

$ port rdeps pdf2djvu
The following ports are dependencies of pdf2djvu @0.7.13_0:
...
  djvulibre
    ImageMagick
...
$ /opt/local/var/macports/sources/svn.macports.org/trunk/base/portmgr/jobs/port_binary_distributable.tcl -v djvulibre
djvulibre is distributable


I am confused as to why pdf2djvu with GPL-2 and no direct dep on ImageMagick is not distributable while djvulibre with GPL-2+ and a direct build dep on ImageMagick is distributable.
