I can see *png pics, but i’ve got problem while ./configure:

checking for SDL - version >= 1.2.4… yes
checking for jpeg_CreateDecompress in -ljpeg… (cached) yes
checking for png_create_read_struct in -lpng… (cached) no
configure: warning:
*** Unable to find PNG library (http://www.libpng.org/pub/png/libpng.html)

checking for uncompress in -lz… (cached) yes
