[Dillo-dev] configure message?

What does this message mean? I am running fedora 15 and I have both pkg-config as well as the following packages installed: libpng-1.2.46-1.fc15.x86_64 libpng10-devel-1.0.55-1.fc15.x86_64 libpng-devel-1.2.46-1.fc15.x86_64 libpng10-1.0.55-1.fc15.x86_64 Here is the relevant portion: there is no libpng14 on fedora, but there is mingw32-libpng-1.4.8-1.fc15.noarch which puts libpng14-config strangely into /usr/i686-pc-mingw32/sys-root/mingw/bin/libpng14-config. checking for libpng-config... which: no libpng14-config in (/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin) /usr/bin/libpng12-config checking for libpng version... 1.2.46 (newer version) ..... everything else compiles "fine"....
