#61121: pihpsdr: Doesn't use MacPorts LDFLAGS
------------------------+----------------------
 Reporter:  ryandesign  |      Owner:  ra1nb0w
     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.3
 Keywords:              |       Port:  pihpsdr
------------------------+----------------------
 pihpsdr fails to build on 10.6 because although it includes the
 legacysupport portgroup it evidently doesn't use MacPorts LDFLAGS so it
 still fails to link with the legacysupport library which would have
 provided getline and clock_gettime:
