Bug#504220: Missing dependencies

[Reinhard Tartler]

digging a bit further in the configure script:

enabled libdc1394 && append pkg_requires "libraw1394"
enabled libdirac  && append pkg_requires "dirac"
enabled libtheora && append pkg_requires "theora"
enabled libvorbis && append pkg_requires "vorbisenc"
[...]
# build pkg-config files

pkgconfig_generate(){
name=$1
shortname=${name#lib}
comment=$2
version=$3
libs=$4
requires=$5
cat <<EOF > $name/$name.pc
prefix=$prefix
exec_prefix=\${prefix}
libdir=$libdir
includedir=$incdir

Name: $name
Description: $comment
Version: $version
Requires: $(disabled shared && echo $requires)
Requires.private: $(enabled shared && echo $requires)
Conflicts:
Libs: -L\${libdir} -l${shortname} $(disabled shared && echo $libs)
Libs.private: $(enabled shared && echo $libs)
Cflags: -I\${includedir}
EOF
cat <<EOF > $name/$name-uninstalled.pc
prefix=
exec_prefix=
libdir=\${pcfiledir}
includedir=${source_path}

Name: $name
Description: $comment
Version: $version
Requires: $requires
Conflicts:
Libs: \${libdir}/${LIBPREF}${shortname}${LIBSUF} $libs
Cflags: -I\${includedir}
EOF
}
pkgconfig_generate libavcodec "FFmpeg codec library" "$LIBAVCODEC_VERSION" "$extralibs" "$pkg_requires libavutil = $LIBAVUTIL_VERSION"
pkgconfig_generate libavformat "FFmpeg container format library" "$LIBAVFORMAT_VERSION" "$extralibs" "$pkg_requires libavcodec = $LIBAVCODEC_VERSION"

That indicates that Requires.private is indeed used on purpose. [1]
indicates that you are right, and the -dev packages are indeed missing
depedencies. However I'd love to see some more authoritative
documentation on that topic, because the difference between Libs.private
and Requires.private is still very unclear to me.
