Comment (by mascguy):

 Replying to [comment:11 mascguy]:
 > As for the SIP-related error regarding mismatched Team IDs, that is
 legit: `port-tclsh` is loading the `libtdbc` dylib from the `tcl` port,
 rather than `${prefix}/libexec/macports/lib/...`. And the adhoc-signed
 binaries from the port, don't have a Team ID set. Whereas MacPorts base
 binaries do.

 Ah, found it: comment:3:ticket:64507:

 And the fix, which works: comment:5:ticket:64507:

 To fair, I didn't try replacing `port-tclsh` with a shell script. Rather,
 I executed `tclsh8.6` from the `libexec` area:

 {{{
 $ /opt/local/libexec/macports/bin/tclsh8.6
 jobs/port_binary_distributable.tcl -v openjdk17
 "openjdk17" is distributable
 }}}
