Currently the graphics/exiv2 port installs the libexiv2 library with the
	name libexiv2-0.9.1.so which is IMO really bad, as the library will not
	show up in the "ldconfig -r" output and other ports which depend on the
	graphics/exiv2 library have to set the dependency by using:
	BUILD_DEPENDS=	exiv2:${PORTSDIR}/graphics/exiv2
	RUN_DEPENDS=	${BUILD_DEPENDS}

	The main problem is that the library is created by using libtool in
	mode=link with the -release argument, which leads to this obscure
	library name.
	The patch modifies the libtool call to use -version-number instead of
	-release and the resulting library will get the name libexiv2.so.0.
	With this name, the library will show up in the "ldconfig -r" output
	and other ports can depend on it in the usual way:
	LIB_DEPENDS=	exiv2.0:${PORTSDIR}/graphics/exiv2

	Makefile:
	- bump PORTREVISION for the library name change

	pkg-plist:
	- chase the new library name

	files/patch-src::Makefile (new)
	- adopt the libtool call to generate the library with a better/correct
	  name

	The only port that depends on graphics/exiv2 is graphics/kphotoalbum
	and I've verified that the patch will not break it with a tinderbox run
	on RELENG_6 i386.

	Patch tested on:	RELENG_4	i386 (tinderbox)
				RELENG_5	i386 (tinderbox)
				RELENG_6	i386 amd64 (tinderbox)
				CURRENT		i386 (tinderbox)

Fix: - apply the patch
	- add files directory to CVS
	- add files/patch-src::Makefile to CVS
