Log message:
Avoid extra stat() calls by not repeatedly checking whether a file
exists on the disk -- we can just check whether a variable defined by
find-files.mk is "__nonexistent__" or not.

Log message:
Export a publicly readable variable PFCTL that contains the path to the
"pfctl" binary.

Log message:
Lower the pflkm dependency from 20041025 to 20040501 (OpenBSD 3.5).
This should fix DragonFly, which seems to have pf from 3.5.

Log message:
Fix directory handling in PLIST. Bump PKGREVISION.

Log message:
Remove USE_PKGINSTALL from pkgsrc now that mk/install/pkginstall.mk
automatically detects whether we want the pkginstall machinery to be
used by the package Makefile.

Log message:
Also check for the pfvar.h file in the subdirectory 'pf', DragonFly installs
it there.

Log message:
Change ONLY_FOR_PLATFORM to NetBSD 2.x.  NetBSD 3 has pf in base so this
pkg is redundant on that version and on -current it doesn't even build
without errors.

Log message:
Fixed pkglint warnings. The warnings are mostly quoting issues, for
example MAKE_ENV+=FOO=${BAR} is changed to MAKE_ENV+=FOO=${BAR:Q}. Some
other changes are outlined in

    http://mail-index.netbsd.org/tech-pkg/2005/12/02/0034.html

Log message:
Add detection for pf from OpenBSD 3.8.

Log message:
The real user name in PKG_USERS does not need to be escaped with double
backslashes anymore. A single backslash is enough. Changed the
definition in all affected packages. For those that are not caught, an
additional check is placed into bsd.pkginstall.mk.
