I'm using Debian 13 (Trixie) on an amd64 server, and trying to compile 
the latest version of Synchronet using the install-sbbs.mk script.  It 
builds correctly but it fails while linking:

```

```

I saw the reference to pthreads but libpthread-stubs0-dev is already 
installed.  I installed all the dependencies, but it seems like I might 
be missing something.  Has anyone seen this error on Trixie before?

Thanks in advance,
