Compilation error on IPFire build system

Dear developers, did a first try to compile netify-agent-v5.0.2 for a IPFire firewall on a specific build system (LFS Linux with glibc 2.38, GCC 13.2.0 & binutils 2.41) as an Addon but get an aclocal error

ipfire build chroot (x86_64) root:/tmp/netify-agent-v5.0.2$ ./autogen.sh 
+ SUBDIRS='libs/gperftools libs/ndpi'
+ for d in $SUBDIRS
+ cd libs/gperftools
+ ./autogen.sh
./autogen.sh: line 7: ./autogen.sh: No such file or directory

autoreconf: export WARNINGS=

aclocal: error: configure.ac:4: file 'm4/ax_pkg_installdir.m4' does not exist
autoreconf: error: aclocal failed with exit status: 1
+ exit 1

does someone may have a short notice how to fix this ?

Best regards,

Erik
