#61494: gcc9 @9.3.0 "Failed to build libgcc9: command execution failed" in macOS
11.0 Big Sur
---------------------------------+--------------------------
 Reporter:  kgerheiser           |      Owner:  (none)
     Type:  defect               |     Status:  new
 Priority:  Normal               |  Milestone:
Component:  ports                |    Version:  2.6.4
 Keywords:  gcc9 libgcc9 bigsur  |       Port:  gcc9 libgcc9
---------------------------------+--------------------------
 I updated to Big Sur and attempted to build GCC9 and it fails. GCC 10
 worked.

 First, there was an error that it couldn't find the command `gsed`, so I
 installed it with MacPorts.

 Then, more errors:

 Looks like it's picking up the macOS version incorrectly and then thinking
 it's macOS 10.4?
