#48649: qgis install fails due to qt4-mac/qt5-mac conflict

     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.3
 Keywords:          |       Port:  qgis
--------------------+--------------------------------
 A recent "upgrade outdated" triggered an error attempting to install
 qt5-mac as a dependency of gpsbabel, due to its conflicting with the
 installed qt4-mac.  After removing qt4-mac and its dependencies, the
 gpsbabel upgrade worked, but  it's now not possible to reinstall qgis due
 to its dependency on qt4-mac.  With any luck, it can be updated to use
 qt5-mac instead, though there may be complications with the py27-qt4 and
 py27-qscintilla dependencies as well.

 More generally, it would be nice to have a better way to handle versioned
 dependencies than the situation typified by this.
