Comment (by essandess):

 Groan, sorry. I’ll post a fix. I think there are three related issues
 here:
 1. This specific bug.
 2. The `tcl` code that makes @mascguy’s brain hurt (mine too, evidently):
 https://github.com/macports/macports-
 ports/pull/14354#discussion_r835502075
 3. The necessary `depends_lib` on `curl-ca-bundles and `apple-pki-bundle`
 needed to update `trustedCAs.pem` Whenever these ports are updated, but
 also unnecessarily rebuilds and installs the `privoxy` binary.

 For 2: Chris, are you able to point to a cleaner `tcl` implementation of
 essentially file output operators like `>>`, but in `tcl`, not `bash`?

 For 3: I think the cleanest approach is to add a subport that installs
 `trustedCAs.pem`, and move the `depends_lib`‘s  to that subport.

 Comments/feedback on any of this?
