Here's a fork that might unbreak the port, https://github.com/Rogach/electricsheep/tree/fix-ffmpeg5 . Upstream appears to be dead so might be worth considering removing this port.
Sweet! <https://www.freshports.org/graphics/electricsheep/> Unfortunately, on FreeBSD 15.0-CURRENT, % ./autogen.sh && ./configure && make Preparing the electricsheep build system...please wait Found GNU Autoconf version 2.71 Found GNU Automake version 1.16.5 Warning: libtoolize does not appear to be available. This means that the automatic build preparation via autoreconf will probably not work. Preparing the build by running each step individually, however, should work and will be done automatically for you if autoreconf fails. ERROR: Unable to locate GNU Libtool. ERROR: To prepare the electricsheep build system from scratch, at least version 1.4.2 of GNU Libtool must be installed. autogen.sh does not need to be run on the same machine that will run configure or make. Either the GNU Autotools will need to be installed or upgraded on this system, or autogen.sh must be run on the source code on another system and then transferred to here. -- Cheers! % pkg provides bin/libtoolize Name : libtool-2.4.7_1 Comment : Generic shared library support script Repo : FreeBSD Filename: usr/local/bin/libtoolize Name : libtool-2.4.7_1 Comment : Generic shared library support script Repo : poudriere Filename: usr/local/bin/libtoolize % sudo pkg install -r FreeBSD libtool Updating FreeBSD repository catalogue...

Friendly ping
There's also a discussion about this license in bug#273952.
Please disregard my last comment - it was for a wrong issue.
Deprecated in a2893d343e8da3ab233315c34e0e6ecf2024974e due to maintainer timeout (wrong PR, sorry)
