clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hi,

I am on my macOS ventura 13.0.1.

Followed the instructions and got:

```
make all

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [bin/dnacat] Error 1
make[1]: *** [seq_file] Error 2
make: *** [libs-core] Error 2
```

xz installed through brew.

Any hint?

Much appreciated,
-A
