Comment (by cardi):

 Can you post the contents of your `$PATH` environment variable?

 It should be look something like:
 {{{
 $ echo $PATH
 /opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
 }}}

 Depending on how you installed MacPorts, your `$PATH` should be properly
 set in `.bash_profile`, `.profile`, or `.bashrc` to include
 `/opt/local/bin` and `/opt/local/sbin` at the beginning (see
 [https://guide.macports.org/chunked/installing.shell.html#installing.shell.postflight]).

 [https://git.zx2c4.com/wireguard-tools/tree/src/wg-quick/darwin.bash#n1
 wg-quick] executes bash using `/usr/bin/env bash`. `/usr/bin/env` looks
 through the directories in `$PATH` and uses the first entry matching
 `bash`. If your `$PATH` has `/bin` before `/opt/local/bin`, executing
 `bash` will use the old, built-in version instead of the newest (the
 latest version of `bash` is installed as a dependency of wireguard-tools).
