Dear -doc and -ports people,
Please review attached patch, which intended to replace outdated
ldconfig-related chapter in Porter's Handbook with one matching reality
(INSTALLS_SHLIB).
-Maxim

+ <para>If your port installs a shared library(ies), define a
+ <makevar>INSTALLS_SHLIB</makevar> make variable, which will instruct
+ a <filename>bsd.port.mk</filename> to run
+ <literal>${LDCONFIG} -m</literal> on the directory where the
+ new library is installed (usually
+ <filename><makevar>PREFIX</makevar>/lib</filename>) during
+ <maketarget>post-install</maketarget> target to register it into the
+ shared library cache. Also this variable, when defined, will
+ facilitate addition a appropriate
+ <literal>@exec /sbin/ldconfig -m</literal> and
+ <literal>@unexec /sbin/ldconfig -R</literal> pair into your
+ <filename>pkg/PLIST</filename> file, so that a user who installed

- library is there. These lines should immediately follow the line
- for the shared library itself, as in:</para>
+ library is there.</para>
+ <para>If you need, you can override default location where the new
+ library is installed by defining <makevar>LDCONFIG_DIRS</makevar>
+ make variable, which should contain list of directories into which
+ shared libraries are to be installed. For example if your port
+ installs shared libraries into
+ <filename><makevar>PREFIX</makevar>/lib/foo</filename> and
+ <filename><makevar>PREFIX</makevar>/lib/bar</filename> directories
+ you could use the following in your

-lib/libtvl80.so.1

+INSTALLS_SHLIB= yes

- <para>Never, ever, <emphasis>ever</emphasis> add a line that says
- <literal>ldconfig</literal> without any arguments to your
- <filename>Makefile</filename> or <filename>pkg/PLIST</filename>.
- This will reset the shared library cache to the contents of
- <filename>/usr/lib</filename> only, and will royally screw up the
- user's machine ("Help, xinit does not run anymore after I install
- this port!"). Anybody who does this will be shot and cut in 65,536
- pieces by a rusty knife and have his liver chopped out by a bunch of
- crows and will eternally rot to death in the deepest bowels of hell
- (not necessarily in that order…)</para>
+ <para>Note that content of <makevar>LDCONFIG_DIRS</makevar> is passed
+ through sed just like the rest of <filename>pkg/PLIST</filename>,
