[Debian 13] Failure to Build Deb Package -- "Cannot read pkg/debian/control"

I'm trying to build a deb file so I can install libsmbios and the utilities.
I cloned the repo and attempted to build the deb file as described.

Error:
```
root@andromeda1:~/gitRepos/libsmbios/pkg# ./mk-rel-deb.sh

dpkg-checkbuilddeps: error: cannot read pkg/debian/control: No such file or directory, installing
Error: Unable to locate package dpkg-checkbuilddeps:
Error: Unable to locate package error:
Error: Unable to locate package cannot
Error: Unable to locate package read
Error: Unable to locate package pkg/debian
Error: Unable to locate package No
Error: Unable to locate package such
Error: Unable to locate package or
Error: Unable to locate package directory

```

What should I do?

Start by reading pkg/mk-rel-deb.sh and checking why it looks for pkg/debian/control when run from the pkg directory. Reproduce the command on Debian 13 and verify the expected control-file path and package-building prerequisites. Done means the documented build command completes and produces the deb package.
