#51298: libgcc and libgcc-devel interfere
------------------------+----------------------------------
 Reporter:  dstrubbe@…  |      Owner:  mww@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.3.4
 Keywords:              |       Port:  libgcc, libgcc-devel
------------------------+----------------------------------
 There is some kind of problem with libgcc and libgcc-devel, such that they
 cannot activate and deactivate cleanly in the presence of the other.
 Possibly this is related to the warnings that the Portfile from the
 registry could not be executed.

 $ sudo port activate libgcc
 --->  Computing dependencies for libgcc
 Warning: Failed to execute portfile from registry for libgcc @5.2.0_0
 --->  Activating libgcc @5.2.0_0

 libgcc-devel port.  Please deactivate this port first, or use 'port -f
 activate libgcc' to force the activation.
