Yeah, sorry. Have a look here for all the changes:
https://gitlab.com/sane-project/backends/-/merge_requests/853/diffs#d20bd4c65270e6b76cbb764eaebb98c4823f0bda

In particular, there is a library addition to the Makefile.am in the
backend directory on line 1622 to add the $(MATH_LIB) variable to the front
of that line.

There was an error that I accidentally introduced. That has been fixed now
but I did get this from the PPA build as well.
Honestly, I would take the source package as-is from Debian, update that
Makefile.am and the rts8891*.* source and it should build the package.

I'm going to be pretty busy this weekend, but I will try to find time to
have a go myself as well to make sure that the process works.

Cheers,
Ralph
