Looking into other matters, I figured out some more.
Is this the bld_prepare.sh as currently is in master:
https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerra-5.1/blds/bld_prepare.sh;h=402b626719899d88e85f233ce5c874ca410d4e58;hb=refs/heads/master
I think it it (I have only so much time).
I downloaded it and diffed it with the modified one that worked for me, and
the:
libdc1394-22-dev
is still in it, and likely shouldn't be.

These are the Debian versions:

Buster = oldstable
Bullseye = stable
Bookworm = testing
Sid = unstable
---
The first three change with time, e.g. Buster was stable, now is oldstable. Bullseye was testing, now is stable, and so forth.
And here's why I write it.

For clarity, this is what I changed (so you don't have to look up old emails, for this part):

This is the:

diff <as-I-found-it-back-10-or-so-days-ago>/blds/bld_prepare.sh  <as-I-changed-it>/blds/bld_prepare.sh

The way to find out if, allow quick paste: 
> But these changes, if they're not in Debian stable already
is look up on packages.debian.org pages, like:

https://packages.debian.org/bullseye/2to3 Look at that! This package is in stable!
https://packages.debian.org/buster/2to3   It is in oldstable too! Different version though.
https://packages.debian.org/bookworm/2to3 Different version in testing as well, take a look!

https://packages.debian.org/buster/python But python is also in oldstable.
https://packages.debian.org/bullesys/python However not in stable anymore. The changes have caught!

However it really takes somebody with probably best stable Debian to test
building from source.
This only helps a bit, I hope.

IOW, the bld_prepare.sh is likely still not good, I'm afraid.

I know it's bad news, and I'm only able to give it this much time. Because of
other work, I have had time to encode with Cinelerra for even less time yet
than it took me to prepare for this email, since I installed it a week ago.

Thanks for your patience!
