I need to install automake-1.9 on macOS Sequoia 15.3.1 Automake 1.9 was released in 2004. I'll be surprised if it works on the latest mac.
In any case, you'll need to replace config.sub, and perhaps other such common files, with the latest versions, after unpacking. You can download the latest from https://git.savannah.gnu.org/cgit/config.git/plain/config.sub For the latest version of other files, if need be, see https://git.savannah.gnu.org/cgit/gnulib.git/tree/build-aux Closing this report, we can't change automake-1.9 ... --thanks, karl.
