The problem was also reported on
https://forum.linuxcnc.org/9-installing-linuxcnc/45634-current-master-2-9-building-debs-error
and I can confirm this locally. Above URL points to my changes to
debian/rules in https://github.com/LinuxCNC/linuxcnc/pull/1700 that have
not yet been merged with master. I need to investigate. Help would be
appreciated.

Thank you for looking at this!
(My purpose reporting here is the understanding that we're trying to debug
to get sid into stable Bookworm with LinuxCNC, and I also want LinuxCNC
working on my little SBC.)
This is potentially helpful, but doesn't immediately clear things up for
me...
Here's what I did after getting this email:
I found the following libtiff packages on my SBC:
libtiff-dev 4.4.0-2
libtiff5 4.4.0-2
libtiffxx5 4.4.0-2
When I search the debian repository, it lists these as unstable (I presume
because we're on sid).
But it also lists them as the most recent releases, not the releases from
Buster (4.2.0-1).
Trying to follow the threads further, I went after the error message you
pointed out and saw it's trying to get: libtifftcl4.1.0.so
I searched the debian repository and nothing by the name of libtiffcl4
exists:
"You have searched for packages that names contain libtifftcl in all
suites, all sections, and all architectures.
Sorry, your search gave no results"
Interestingly, the Sourceforge branches for tkImg does not have a *branch*
for 1.4 (which appears to be what the line above is looking for)
https://sourceforge.net/p/tkimg/code/HEAD/tree/branches/
But there *is* a version 1.4.13 under tags:
https://sourceforge.net/p/tkimg/code/HEAD/tree/tags/1.4.13/
I downloaded that 1.4.13 source and used MS Code to search the downloaded
source and found a piece of code compat/libtiff/libtiff/libtiff.map that
has the string " LIBTIFF_4.0" in it.
I found 8 files that have _TIFFsetString in it.
But I don't understand the compiling setup well enough to see how those
files get compiled to create an object named libtifftcl4.1.0.so (??)
(there is no string in the source for libtifftcl4)
I'm happy to try and dig further, but I'm also at a stop point.

This looks to be a dependency (hard coded?) on the version of libtiff
that shipped with Buster (4.1).
But it also seems to be in a package that LinuxCNC depends on, but
doesn't control?
https://sourceforge.net/projects/tkimg/files/tkimg/1.4/tkimg%201.4.13/
(From the file path being searched)
For me, the trail dries up there. I guess this is due to a Tcl/Tk
dependency?
