The summarized fix:
find /usr/share/man -exec test -e {}.gz \; -exec tar rzvPf ~/man.tgz {} \;
sudo find /usr/share/man -exec test -e {}.gz \; -exec rm {} \;
Your 10.4 manpages will be backed up to ~/man.tgz
and then removed.
If you have a case-sensitive file system, see the comment by sEEKz on the hint page.
