Just asked for libbpf-dev to be installed on the debian:11 container:

[perfbuilder@...e 11]$ dsh debian:11
$ bash
perfbuilder@...d1572e8cf:/$ ls -la /usr/lib/x86_64-linux-gnu/libbpf.so.0
lrwxrwxrwx. 1 root root 15 Jan 10  2021 /usr/lib/x86_64-linux-gnu/libbpf.so.0 -> libbpf.so.0.3.0
perfbuilder@...d1572e8cf:/$ dpkg -l | grep bpf
ii  libbpf-dev:amd64                   1:0.3-2                        amd64        eBPF helper library (development files)
ii  libbpf0:amd64                      1:0.3-2                        amd64        eBPF helper library (shared library)
