Dear. GnuPG-Users.

When making "libgcrypt ver1.10.2" and "libgcrypt ver1.8.10",
I got the following error and the compilation could not proceed.
(Output is line-breaked where appropriate.)

Unfortunately I don't know how to make this 'make' passable.

I am very sorry that this is not about "GnuPG".
Could you please advise me how to avoid this error?

My environment is as follows.
Also, ". /configure" output is attached.

OS         :  macOS  13.3.1 (a) / Command Line Tools for Xcode 14.3
Platform :  Darwin (x86_64-apple-darwin22.4.0)

Sincerely yours.
