 When trying to upgrade julia from 0.3.8 to 0.3.9, or install julia @0.3.9

 This occurs whether upgrading the existing port, or cleaning then
 installing julia +gcc48.  I haven't tried installing gcc49 and using the
 julia +gcc49 (default) variant on this machine, but another machine (2013
 Mac Pro) with gcc49 upgrades without issue, so I suspect this may be a gcc
 version problem.

 I am on MacPorts trunk r139164, OS X 10.10.4.
