 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.6.2
 Keywords:          |       Port:  clang-3.7
--------------------+-----------------------
 I am unable to upgrade clang-3.7 on my Mac running Lion.
 Macports is using libc++

 The command "sudo port upgrade clang-3.7" just crashes and hangs.

 I need to look at the console to see the crashes for the various threads!
 Please see the attached crash reports from my console.

 Any ideas on a solution would be greatly appreciated.
