 I first received this error when I tried to install py39-jupyter, which
 depends on py39-six:

 {{{

 }}}

 I followed the  migration instructions
 [https://trac.macports.org/wiki/Migration] to start with a fresh
 installation.

 After uninstalling all of my ports and cleaning partial builds (steps c
 and d), I followed the instructions at
 [https://trac.macports.org/wiki/ProblemHotlist#reinstall-clt] to reinstall
 the command line tools.

 After reinstalling the command line tools, I used the script
 restore_ports.tcl to re-install my previous ports and at first py39-six
 appeared to install correctly:


 {{{

 --->  Cleaning py39-six
 }}}

 However later in the process, when py39-six activation was required as a
 dependency of gobject-introspection I observed a similar error as with
 jupyter:


 {{{

 details.

 }}}

 The same problem manifested for all subsequent packages that depend on
 py39-six. I've attached the referenced log file, along with the
 "myports.txt" list of my previously installed ports that I was trying to
 re-install.
