PHP did not find your libjpeg. Specify where it is using
--with-jpeg-dir=<DIR>

Ok, good, PHP found your libpng

Make sure you did a "rm config.cache" before running configure. If you
did, then double check that your libgd was actually compiled with PNG
support. It is not enough that libpng is on your system and that PHP
finds it, GD has to have been built against it as well. A quick way to
check which imahge types your libgd was built to support is to do:
nm -o /usr/lib/libgd.a | grep -i imagecreatefrom
> checking for gdImageCreateFromJpeg in -lgd... (cached) no
Again, it doesn't look like your GD library has jpeg support.
I would suggest using GD2. It really is much better than GD 1.x in most
respects. Grab the gd-2.0.1 tarball, expand it somewhere and check the
Makefile and make sure it has:
CFLAGS=-g -DHAVE_LIBPNG -DHAVE_LIBJPEG -DHAVE_LIBFREETYPE
LIBS=libgd.a -lpng -lz -ljpeg -lfreetype -lm
(make sure you have freetype2 installed before continuing)
then type: make libgd.a
Don't bother installing it anywhere, just point PHP directly at this gd2
directory. I use these PHP configure switches:
--with-gd=/home/rasmus/gd-2.0.1
--with-freetype-dir=/usr
--enable-gd-native-ttf
--enable-gd-imgstrttf
--with-jpeg-dir=/usr
--with-png-dir=/usr
--with-xpm-dir=/usr/X11R6
--with-zlib
Note there was a slight buglet in 4.0.6 and you might have to use:
--enable-gd-native-tt instead of --enable-gd-native-ttf
