Difficulty using gnunet on Debian 12

Hello,

Debian 12 includes gnunet 0.19.3. I followed the handbook with
`gnunet-arm -s` and then `gnunet-arm -I` listed peers, but
`gnunet-core` came up empty. I saw some errors under ~/.cache/gnunet
logs.

The handbook advises that there might be a network configuration
issue, but this seems a package version issue.

I tried to compile the latest release tarball, 0.21.1, but no luck
again at the make step: first a complaint that <extractor.h> is
missing, which comes from libextractor. Somehow the configuration
script didn't catch this dependency. I fixed that. Then another issue
that "did_core.h" is missing, even though I have it under
./src/service/reclaim/did_core.h.

What is the recommended way to try out gnunet?

Regards,
