Tweak RUN_DEPENDS, switching to file-based django detection, instead of by package name. This ensures that if a port that depends on this one, also depends on a different django version, it will see and use the installed version, rather than attempting to install another one, which results in a conflict as all django ports conflict with each other. www/py-django-dpaste depends on py-django-mptt but is about to be limited to Django <= 1.6 (it does not currently support higher). Since py-django-mptt depends on www/py-django (currently 1.8.x), this results in the conflict described above. The same change will also be made in www/py-django-dpaste for any ports that may depend on *it* in the future. This change is a NOOP for other conditions. See r390184 [1] for another instance of this issue. [1] https://svnweb.freebsd.org/changeset/ports/390184 Approved by: portmgr (blanket: trivial, tested, build fixes)
