It looks like that elpa-pdf-tools does depends on dh-elpa-helper and
emacsen-common on Bookworm which should take care of the byte
compiling[1]. I also installed elpa-pdf-tools and ran "M-x
pdf-tools-install" successfully, and "M-x pdf-tools-help" also works
fine. The "Warning (comp)" is just a warning for native compilation
which is usually harmless.
It would be great if you can generate a bug report using "reportbug" or
"M-x debian-bug" which will include more info about the package, its
dependencies, and your system. Also if you see any command that fails
run, it would be good to have a backtrace attached in the report.
