Missing libraries?

[csant]

Hi,

after a cvs up today, emacs configure script claims errors - these are the  
last lines:

        checking png.h usability... yes
        checking png.h presence... yes
        checking for png.h... yes
        checking libpng/png.h usability... yes
        checking libpng/png.h presence... yes
        checking for libpng/png.h... yes
        checking for png_get_channels in -lpng... no
        checking tiffio.h usability... yes
        checking tiffio.h presence... yes
        checking for tiffio.h... yes
        checking for TIFFGetVersion in -ltiff... no
        checking gif_lib.h usability... yes
        checking gif_lib.h presence... yes
        checking for gif_lib.h... yes
        checking for EGifPutExtensionLast in -lgif... no
        checking for EGifPutExtensionLast in -lungif... no
        configure: error: The following required libraries were not found:
            libXpm libjpeg libpng libgif/libungif libtiff
        Maybe some development libraries/packages are missing?
        If you don't want to link with them give
	    --with-xpm=no --with-jpeg=no --with-png=no --with-gif=no  
--with-tiff=no
        as options to configure

Nothing in my build environment has changed - why are those libs suddenly  
"missing"?  Or is just a different version of those libs required now?
