 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.3.99
 Keywords:  haspatch      |       Port:  HexFiend
--------------------------+----------------------
 HexFiend 2.1.2 doesn't build on current OS X / Xcode because it uses
 garbage collection which is no longer supported. The developers already
 fixed this but hadn't released a new version. I convinced the developers
 to release a new version, which they called 2.3.0. It now requires Lion or
 newer. The attached patch updates the port and works for me on Mavericks.
 The files directory should be deleted.
