In the current version of ports/japanese/lynx (ja-lynx-2.8.4.rel1),
there are two problems about installation and deinstallation.

(1) First, if you run 'make install' in the port directory, a newly
    installed configulation file 'lynx.cfg' (not old one) is renamed
    to 'lynx.oldcfg' by mistake (and the another version of 'lynx.cfg'
    is installed later).

    This failure is occured by a wrong patch description (patch-aa).

    Then if you run 'make deinstall', the file 'lynx.oldcfg' is
    renamed to 'lynx.cfg' and leaved alone by the deinstall script
    described in pkg-plist.  This step is correct if the file
    'lynx.oldcfg' is a true backup file...

(2) If you install or deinstall the software from a binary package,
    that causes error messages due to the port's wrong pkg-plist
    lines:

$ cat -n /usr/ports/japanese/lynx/pkg-plist | head -n 6
     1 bin/lynx
     2 etc/lynx.cfg.sample
     3 @exec test -f %B/lynx.cfg && mv -f %B/lynx.cfg %B/lynx.oldcfg
     4 @exec cp -f %D/%F %B/lynx.cfg
     5 @unexec rm -f %B/lynx.cfg
     6 @unexec test -f %B/lynx.oldcfg && mv -f %B/lynx.oldcfg %B/lynx.cfg
$

    Whether the test(1) commands (in line 3 and 6) has failed or not,
    the aim of these lines are archived.

    But if the test(1) command has failed, pkg_add(8) and
    pkg_delete(8) commands outputs an error message.

Fix: * Fix these installation/deinstallation problems.
 * Update to the latest stable release (lynx2.8.6rel.4).
 * Remove patch-ab and patch-ad.  I've been tested lynx2.8.6 without
   the latter patch that is CJK specific. It seems that there is no
   problem.

The patch file (patch-aa), pkg-plist, and Makefile are based on
ports/www/lynx.
How-To-Repeat: # cd /usr/ports/japanese/lynx
# find /usr/local | sort > before-install.txt
# make TRYBROKEN=yes install package deinstall
===>   NOTICE:

This port is deprecated; you may wish to reconsider installing it:

Leaves behind config file on deinstall.

It is scheduled to be removed on or after 2007-04-10.
