The latest libassuan is failing to build on macOS 15.1.1. I already have 
a recent GnuPG installed from Homebrew, but wanted to look at 2.5.2.

Configuration flags used: --enable-static
Compiler info:
	Apple clang version 16.0.0 (clang-1600.0.26.4)
	Target: arm64-apple-darwin24.1.0
	Thread model: posix
Output:
