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

 {{{

 }}}

 I followed the  migration instructions 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 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:


 {{{
 --->  Computing dependencies for py39-six
 --->  Fetching archive for py39-six
 --->  Attempting to fetch py39-six-1.16.0_0.darwin_19.noarch.tbz2 from

 from https://packages.macports.org/py39-six
 --->  Installing py39-six @1.16.0_0
 --->  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:


 {{{
 --->  Activating py39-six @1.16.0_0
 Error: Failed to activate py39-six: Image error:
 /opt/local/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9

 .org_macports_release_tarballs_ports_python_py-six/py39-six/main.log for
 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.

Comment:

 It seems unlikely that this is a bug in MacPorts base or in any MacPorts
 port. It seems more likely that something outside of MacPorts installed
 this file into the MacPorts prefix, thereby causing this problem for
 MacPorts. The solution would be to manually remove the file and to refrain
 from running whatever process put those files there in the first place.
