Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Decorate .endif with the name of the variable the .if tested.

Log message:
Cast ne_crc to int32_t as expected by the regression tests. On LP64
systems, it would not be negative otherwise.
clearsilver-base is destdir ready, mark it so. clearsilver itself is
a meta package, mark it so.

Log message:
Switch to Python 2.5 as default. Bump revision of all packages that have
changed runtime dependencies now.

Log message:
Update clearsilver packages to 0.10.5.

Changes:
- GCC printf attributes for all printf like functions for better
  compiler time warnings (Nikolai Kondrashov)
- Better support for other compilers for handling CPP variable
  argument macros (Raphaël HUCK)
- Fix for some symlinking/hdf_get_obj bugs (Nikolai Kondrashov)
- Performance improvements to Perl wrapper (Sergey Skvortsov)
- New url_validate Clearsilver method (Mugdha Bendre @ Google)
- Quick Hello World example for using with FastCGI (Mike Tsao @ Google)
- Updates to the Ruby wrapper (Dan Janowski)
- Updates to the Java wrapper (Joe Walnes @ Google)
- Add support to Java wrapper for hooking the file loader
- Add string.crc builtin-function
- Make it easier to write XSS free clearsilver code
- Ability to setup file load hooks for cs and hdf files
- fix for non-thread safe nerr_init call (causes java jni wrapper to
  core dump when server is started under heavy load)
- python egg support (if you have the egg version of distutils
  installed)
- some parser edge case fixes.
- some cleanups to cgiwrap that make it easier to use with
  fastcgi.  fastcgi wrapper to come in the future.

Log message:
Set MAINTAINER to pkgsrc-users@.

Log message:
Use -fPIC in more places; fixes broken amd64 build and perhaps others.
Fix a long/int type mismatch hidden by use of ... and va_arg; fixes
broken LP64 builds.

Log message:
- ruby-clearsilver switch to use vendor_dir with Ruby 1.8.7.

Bump PKGREVISION.

Log message:
* If PLIST_SRC is explicitly set to an empty value in a package Makefile,
  then automatically generate a PLIST that says "${PKGNAME} has no files".

* If PLIST_SRC and GENERATE_PLIST are not set in a package Makefile,
  and no PLIST files exist, then fail during the package build with
  PKG_FAIL_REASON.

* Remove "intentionally empty" PLISTs again.

Now, the easy way to say that a package installs no files is to just
add the following to the package Makefile:

	PLIST_SRC=	# empty

Log message:
Re-add "intentionally empty" PLISTs for meta-packages and other packages
that directly manipulate empty PLISTs.

Modify plist/plist.mk so that if the PLIST files are missing and no
GENERATE_PLIST is defined, then the package fails to build.
