Comment (by herbygillot):

 I had discovered this exact same issue in a PR I opened to update Go:
 https://github.com/macports/macports-ports/pull/17559

 But @ci42 summarily updated to 1.20 here: https://github.com/macports
 /macports-ports/commit/01d73a14bfda876e2524d2099605d18b1d61aa4c

 @ci42, please fix.
