> 2) a couple of other packages include %_libdir/pkgconfig by accident,

>   ipod-sharp-devel  499658
>   sane-backends-devel  499659
>   libXScrnSaver-devel  499660
>   freetype-devel  499661
>   anthy-devel  499663

> Since these are multilib'ed, a dependency on /usr/lib/pkgconfig
> doesn't pull in pkgconfig.i386 but one of these -devel packages
