What do you mean by "I combine the lists into a single hierarchy"?
You run the build tool, which outputs to /build_output, then you run
the CMS, which outputs to /cms_output, and then you copy the contents
from /build_output and /cms_output to /combined_output?

This makes it sound like my guess about /build_output and /cms_output
might be right.  It sounds like you update the CMS content using some
opaque tool and then copy the results to your working copy.  If you do
that (and also run the build tool in a directory separate from your
working copy), then why not something like this:

#! /bin/bash

CMS_DIR=...
BUILD_DIR=...
WORKING_COPY=...

(cd "${CMS_DIR}"; find; cd "${BUILD_DIR}; find) | sort | uniq >
/tmp/live_file_list.tmp
(cd "${WORKING_COPY}"; find) | fgrep -v '/.svn/' | sort >
/tmp/working_copy_list.tmp

diff -u /tmp/working_copy_list.tmp /tmp/live_file_list.tmp

The above should (I haven't tested it) produce a list of new files
marked with + and deleted files marked with -.  That information, plus
the output from svn status (after copying the relevant files into the
working copy) should produce new, deleted, and modified lists.
