Good news! ns_eval solved the problem.

set command "pdftk $files cat output $output_file"

ns_eval exec $command

You should use plain eval, not ns_eval.

ns_eval is used for reinitializing all the tcl interpreters in the server, something you generally don't want to be doing a lot of on a production server.
