#64571: libgcc9 build failure on macOS Monterey (12.2) Xcode 13.2.1
------------------------+---------------------
 Reporter:  MarkCallow  |      Owner:  (none)
     Type:  defect      |     Status:  new
 Priority:  High        |  Milestone:
Component:  ports       |    Version:  2.7.1
 Keywords:              |       Port:  libgcc9
------------------------+---------------------
 In what has turned into a very painful migration of my MacPort's installed
 packages from Big Sur to Monterey I have found that the package libgcc9
 won't build. There are "Undefined symbols for architecture x86_64:", when
 linking `gencondmd.o`. Here is the list. I will upload the complete log
 file.

 }}}

 A half-dozen or so of the packages I had installed on Big Sur have a
 dependency on libgcc9 so I'm stuck.
