#58815: unbound @1.9.2: fails to build in trace mode
-----------------------+---------------------
 Reporter:  satraul    |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.5.4
 Keywords:  tracemode  |       Port:  unbound
-----------------------+---------------------
 I have expat installed in both my prefixes /opt/local/ and /opt/macports-
 test/. Installing unbound on /opt/macports-test/ with tracemode fails
 because it tries to access expat.h in /opt/local/
