Comment (by fracai):

 I was able to get this a bit further by modifying: ` .../work/net-
 snmp-5.9/agent/mibgroup/hardware/memory/memory_darwin.c:81`
 to add `|| defined(__aarch64__)` to the end of the line.

 Then the port fails with:

 This looks similar to: #62227, #59951, #62440. So maybe a similar fix?
