and attempting to build again, the re-build fails with the following

dpkg-source: error: aborting due to unexpected upstream changes, see /tmp/freeciv_2.4.3-1.diff.WVHr__
dpkg-source: info: you can integrate the local changes with dpkg-source --commit

If you need more information, please let me know.
