#64189: legacy-support-devel @20211111: "port" wedged after deactivation

------------------------+----------------------------------
 This is a strange one. I have three parallel MacPorts installations. After
 deactivating {{{legacy-support-devel}}} on one of them (with the intention
 of activating {{{legacy-support}}}), none of the port binaries are usable:

 {{{

     (file "/opt/local/bin/port" line 46)
 }}}

 (Similar error when invoking the other {{{port}}} binaries in separate
 installation directories, which is the strangest part.)

 Any ideas on what's going on and how I can un-wedge the system with
 reinstalling MacPorts? Restarted to no avail. 10.4.11/PPC
