Maybe you want to have a look at my debuild control file (purr-data/debuild/debian/control) and update the control file in linux_make/debian accordingly. The debuild stuff is always up-to-date and known to work with every Debian/Ubuntu version younger than Stretch and Xenial, because I'm using it to build packages on the OBS.

Ah, I see. Hm, rather than the old hard-coded deps I should just put a
line to fetch those deps from that file.

And yes, that's really the Python2 version that it needs, which causes quite some headaches if you want to build Purr on both old and new Debian/Ubuntu versions. But you can have a look at purr-data/debuild/debian/control to see how I solved this in the OBS builds. It would be good if we could just get rid of that Python2 dependency, since Python2 is pretty much on its way out.

Ok, my list vs. your "Build-Depends":

1. I've got libjack-jackd2-dev while you have libjack-dev. Any benefit
to one or the other?

2. I've got libglu1-mesa-dev while you do not. Any reason I still need that one?

3. I have libgmerlin-avdec-dev while you do not. But we both have
libgmerlin-avdec-dev.

4. I have dssi-dev while you do not. But you have dssi-utils under "Depends"

5. As mentioned I have slv2-jack and libslv2-dev, you don't.

6. I have libgsl0-dev, you have libgsl-dev

7. I have portaudio19-dev, you don't.

8. I have libsmpeg0, you don't.

9. I have libjpeg62-turbo, you have libjpeg-dev.

10. I have git, you don't

11. I have byacc, you don't.

Hm... wonder why we have libgtk2.0-dev-- was that added for nw.js?
