#61484: dbus-python37 fails to build on Big Sur (symbol(s) not found)
--------------------+---------------------------
 Reporter:  Roarrk  |      Owner:  (none)
     Type:  defect  |     Status:  new
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.6.99
 Keywords:          |       Port:  dbus-python37
--------------------+---------------------------
 I know Big Sur is not officially supported yet, but never the less I
 thought I would file this report as its blocking a few ports from
 installing for me and I have not had success solving it

 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)

 Attached main.log.
