 ***

 NB: I repeatedly checked the installation of Xcode, and the Xcode Command
 Line Tools, but the error seems not to be due to that, but the problem
 seems not to be resulting from there. This seems to be similar to ticket
 #62226 -- I take it from the answer there that this warning should be
 ignored for now.
