Log message:
Bump the PKGREVISIONs of all (638) packages that hardcode the locations
of Perl files to deal with the perl-5.8.7 update that moved all
pkgsrc-installed Perl files into the "vendor" directories.

Log message:
Remove some unnecessarily strong dependencies on perl that resulted
from including perl5/buildlink3.mk.  These packages just need the Perl
interpreter, and can just add "perl" to USE_TOOLS instead.

Log message:
Drop support for TOOLS_DEPMETHOD.<tool>.  The new way to specify a
run-time dependency (DEPENDS) on a tool is to append a ":run" modifier
to the tool name, e.g.,

	USE_TOOLS+=	perl:run

Tools without modifiers or with an explicit ":build" modifier will
cause build dependencies (BUILD_DEPENDS) on those tools to be added.
This makes the notation a bit more compact.

Log message:
Remove trailing empty line introduced in previous.

Log message:
list files which reference ${WRKSRC} in a way which should be ok.  Bump PKGREVISION.

Log message:
Remove explicit dependencies on the GNU m4 package with USE_TOOLS+=m4
and appropriate TOOLS_DEPMETHOD.gm4 settings.

Log message:
Change references to M4 & YACC into TOOLS_M4 & TOOLS_YACC to simplify
transition to new tools framework.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 digests.

Log message:
Remove the redundant PERL="..." setting in CONFIGURE_ENV; it is done
in bsd.pkg.mk.
