 The latest log attached to this still has

 {{{

 /Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/sys/resource.h:

 }}}

 which leads me to suspect you in fact have not updated to get the patch
 that fixes this. Please run

 {{{
 sudo port sync
 sudo port upgrade outdated
 }}}

 and then try again with a clean build attempt.
