I have downloaded BlueZ 5.66 source from http://www.kernel.org/pub/linux/bluetooth/bluez-5.66.tar.xz onto an Ubuntu 22.04 system, and am attempting to build it from source. I have executed the following commands:
apt-get update
sudo apt-get install -y libusb-dev libdbus-1-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev autoconf python3-docutils
cd bluez-5.66
./configure --prefix=/usr --mandir=/usr/share/man --sysconfdir=/etc --localstatedir=/var --enable-experimental
This succeeds, and here's the output just in case it matters:

Am I missing some dependency?
(I would note that these instructions worked for me on earlier versions of BlueZ. Also this page implies these are the right instructions for Ubuntu 22.04))
After searching around more, I found this page that has some helpful output about the missing AC_PROG_LIBTOOL macro. I ran
$ aclocal
$ autoconf
configure.ac:36: warning: The macro `AC_PROG_LIBTOOL' is obsolete.
configure.ac:36: You should run autoupdate.
aclocal.m4:121: AC_PROG_LIBTOOL is expanded from...
configure.ac:36: the top level
And then that gave me the hint to run autoupdate. Once I did that, the compile at least started in earnest. But then I got this error:
libtool: Version mismatch error. This is libtool 2.4.7 Debian-2.4.7-4, but the
libtool: definition of this LT_INIT comes from libtool 2.4.6.
libtool: You should recreate aclocal.m4 with macros from libtool 2.4.7 Debian-2.4.7-4
libtool: and run autoconf again.
make[1]: *** [Makefile:7537: gdbus/mainloop.lo] Error 63
And now I'm not sure how to get past that error.
But in general, does this mean there's an error in BlueZ 5.66 in that it's using AC_PROG_LIBTOOL when it shouldn't be?
