Without more details, this is only a guess but the messages seem to indicate that your build is detecting an installed version of the GNU gettext library, which is optional for Python builds and is not provided by default on macOS, and most likely that version is an Intel-only build of the package and its libintl shared library. Check whether you have an outdated version of gettext and libintl*.dylib installed somewhere, perhaps in /usr/local/, possibly via a third-party package manager like Homebrew or MacPorts, and either remove it or update it with a arm64 (or universal2 fat) build.
