 Replying to [comment:7 clemens.brunner@…]:
 > Thanks, rebuilding tiff from source did get rid of this error message;
 macdeployqt now works as expected.

 We should really revbump tiff some time soon to fix this.

 > I didn't know that manually setting the minimum target when building my
 application had no effect. Do you think that's a MacPorts bug or expected
 behavior?

 That's intended. MacPorts is not affected by any environment variables you
 have set by default. However, setting `macosx_deployment_target` doesn't
 work with all ports correctly either, so chances are setting it might not
 have any effect on `qt4-mac`.

 > On a related note, it would be interesting to know why these situations
 are not handled automatically by MacPorts; if some flags were updated,
 shouldn't all my ports have been rebuilt to ensure consistent operation?

 It's a trade-off; the question is whether we should force all users to
 rebuild all ports because of a rather simple (and meaningless for most
 users) change. Also, we currently don't have a facility in place to
 trigger rebuilding all ports after a MacPorts update -- we only support
 this for OS upgrades. Rev-bumping all ports isn't enough to fix this,
 because some people might still use an older version of MacPorts.
