    Package collection taken with the release of NetBSD-1.5.2.

>Description:
	qcad fails to start, because it misses libpng.so.1, if it
	is installed from the collection of precompiled packages.

>How-To-Repeat:
	Delete all packages qcad depends on from the system and
	install it. The packages it depends on will automaticliy
	installed including "png-1.0.11".

   Start qcad and watch for the error messgage or run ldd on it.

ldd /usr/pkg/bin/qcad:
  /usr/pkg/bin/qcad:
	 -lm.0 => /usr/lib/libm387.so.0
    ...
	 -lz.0 => /usr/lib/libz.so.0
	 -lpng.1 => /usr/pkg/lib/libpng.so.1   !! The result of my work around!!
	 -ljpeg.62 => /usr/pkg/lib/libjpeg.so.62
    ...

pkg_info -L png:
  Information for png-1.0.11:
  Required by:
    qt2-libs-2.3.0
    qcad-1.4.7
  Files:
    /usr/pkg/include/png.h
    /usr/pkg/include/pngconf.h
    /usr/pkg/lib/libpng.a
    /usr/pkg/lib/libpng.la
    /usr/pkg/lib/libpng.so
    /usr/pkg/lib/libpng.so.2
    /usr/pkg/lib/libpng.so.2.0
    /usr/pkg/man/man3/libpng.3
    /usr/pkg/man/man3/libpngpf.3
    /usr/pkg/man/man5/png.5

  As you can see the png-1.0.11 package installes only the version
  2.0 of libpng.so and qcad-1.4.7, which depends on png-1.0.11, requires
  version 1 of linpng.so.

>Fix:
	Link the qcad to an actual version of the png package.

   Work around: "ln -s libpng.so.2.0 libpng.so.1" in /usr/pkg/lib.
     Yes I know that indicates posible incompatible interface changes
     in the library, but i found no problem when working with qcad.
     May be I do not use the part of qcad, which uses libpng.
