----------------------+-------------------

     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.3.5
 Keywords:            |       Port:  vtk5
----------------------+-------------------
 Here are the error details in the last line of my main.log file:  I
 believe the dependency should be spelled '''qt4-mac''' instead of
 '''qt4_mac'''
