"Undefined symbols for architecture x86_64"
-------------------------+-------------------
 Reporter:  ballapete    |      Owner:
     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.4.2
 Keywords:  snowleopard  |       Port:  gcc7
-------------------------+-------------------
 After fftw-3 was built installed port decided to install GCC7. Is
 cxx_stdlib PortGroup missing? Or too much?
