Log message:
Bump for perl-5.20.0.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Log message:
Bump all packages that use perl, or depend on a p5-* package, or
are called p5-*.

I hope that's all of them.

Log message:

Log message:
Cleanup fallout from {DE,}INSTALL_SRC removal: rewrite the INSTALL
script to be of the format expected by the pkginstall framework.
Also, split out the important text from the INSTALL script and put it
into a MESSAGE file.

Log message:
Move the check-shlibs target from bsd.pkg.mk to bsd.pkg.check.mk where
it will live with other "check" targets run after package installation.

Get rid of SHLIB_HANDLING, whose meaning had mutated over the years
from one thing to another.  Currently, it is used to basically note
whether the system's "ldd" command can be usefully run on the package's
binaries and libraries.  Rename this variable to CHECK_SHLIBS_SUPPORTED
for more clarity.

CHECK_SHLIBS is now a variable set exclusively by the user in /etc/mk.conf
to note whether the check for missing run-time search paths is performed
after a package is installed.  It defaults to "no" unless PKG_DEVELOPER
is set.

Log message:
Removed the superfluous "quotes" and 'quotes' from variables that don't
need them, for example RESTRICTED and SUBST_MESSAGE.*.
