Missing libraries?

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?
