Comment:

 Thanks, I'll commit it with some changes.

 The revision should be set to 0 when updating the version.

 There's no need to put quotation marks around the value that you set
 `configure.cmd` (or any other MacPorts option) to. (You only need that
 when setting your own Tcl variables that are not MacPorts options.)

 It's preferable to use `use_autoreconf yes` and adjust `autoreconf.args`
 if necessary rather than doing it manually by overriding `configure.cmd`.
 The default value of `autoreconf.args` is `--install --verbose` so I don't
 think we'll need to change them here.

 I'll fix the description of the python39 variant and set that as the
 default python variant to match what we do in other ports now.
