restore_ports.tcl failure

[Murray Eisenberg]

I’m trying to migrate my ports, originally installed under Catalina (actually, 
migrated from my iMac running Catalina), to Big Sur 11.1 on an M1 MacBook Air. 
When I got to the step

sudo ./restore_ports.tcl myports.txt

I get the following error message:

        list element in braces followed by "#!/bin/sh" instead of space
            while executing
        "foreach op $operationList {
                set name [string trim [lindex $op 0]]
               set variations [lindex $op 1]
                set active [lindex $op 2]

           ..."
            (procedure "install_ports" line 2)
            invoked from within
        "install_ports $operationList#!/bin/sh”
          (file "./restore_ports.tcl" line 287)

This is using the default (zsh) shell in Terminal.

The offending line in the script is:

        install_ports $operationList#!bin/sh

What’s wrong?
