Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

When linking a library libA with a library libB using libtool, if libB.la
exists, libtool will add all libraries libB.la refers to (dependency_libs
field) to the linker command line and store them in the dependency_libs
field of libA.la.  So everything that subsequently links with libA will also
link to these extra libraries.  This causes too much overlinking.

This commit modifies Mk/Uses/libtool.mk so it empties the dependency_libs
field in .la libraries during staging.  However, because .la libraries have
very limited use when dependency_libs is empty it makes sense to completely
remove them during staging.

So with this commit USES=libtool is modified to remove .la libraries and a
new form (USES=libtool:keepla) is introduced in case they need to be kept
(dependency_libs is still emptied).

This release brings initial PackageKit support, Upower (replaces power

Sadly GNOME 2.30.x will be the last release with FreeBSD 6.X support. This

highly-anticipated GNOME 3.0 which will bring with it a new UI experience.

users. Be sure to consult the UPGRADING note or the 2.30 upgrade FAQ at

In particular, kwm brought in Evolution MAPI support for better Microsoft

Presenting GNOME 2.20.1 and all related works for FreeBSD.  The official
GNOME 2.20 release notes can be found at
http://www.gnome.org/start/2.20/notes/en/ .  Beyond that, this update
includes the new GIMP 2.4 (courtesy of ahze).

The GNOME 2.20 update also includes a huge change in the FreeBSD GNOME
hierarchy.  We are now using the more standard DATADIR of ${PREFIX}/share
rather than ${PREFIX}/share/gnome. The result is that fewer patches and
hacks are needed to port GNOME components to FreeBSD.  This will mean some
user changes may be required, so be sure to read /usr/ports/UPDATING for
more details.

This release and the things we accomplished in it would not have been
possible without mezz's crazy idea to collapse DATADIR, and his persistence
to make it happen successfully.  Ahze and pav also deserve thanks for

amount of work by the FreeBSD GNOME Team and our testers.

On top of the usual GNOME update, we have taken this opportunity to move
GNOME from X11BASE to LOCALBASE.  This means roughly 600 ports NOT part of
the GNOME Desktop also need to be changed.  The bulk of the move was carried
out by ahze, mezz, and pav, but it would not have been possible without
cooperation from the FreeBSD KDE team who worked with us to make sure
GNOME and KDE can still coexist happily.  We would also like to send a
shout out to kris and pointyhat for putting up with multiple test runs
until we got something that was solid.

Back to GNOME 2.16.  This release brings a huge amount of new functionality
