Unresolved symbol: DL_UNLOAD (code) in php-4.0.3pl1

Hello, In attempt to get jpeg stuff working with PHP and GD 1.8.3 I unpacked and compiled the latest php .. php-4.0.3pl1 However when I compile it and then install it the apache fails the configtest for this error. /usr/lib/dld.sl: Unresolved symbol: DL_UNLOAD (code) from /opt/Apache/libexec/l ibphp4.so I see that DL_UNLOAD is called in php-4.0.3pl1/ext/standard/dl.c and defined in php-4.0.3pl1/Zend/zend.h Has anyone else seen this problem ? Should I just include zend.h ? I was running, and still have php-4.0.2 which runs fine except I cannot get jpeg stuff to work ... only pnp i.e. this <?php if (ImageTypes() & IMG_PNG) { echo "PNG Support is enabled"; } if (ImageTypes() & IMG_GIF) { echo "GIF Support is enabled"; } if (ImageTypes() & IMG_JPG) { echo "JPG Support is enabled"; } if (ImageTypes() & IMG_WBMP) { echo "WBMP Support is enabled"; } ?> only returns PNG and WBMP ... I know why GIF isn't supported. I am installing on HP-UX 10.20 ... here is my configure options. ./configure --with-mysql --with-apxs=/opt/Apache/bin/apxs --with-gd=yes --with-gd=/opt/gd --with-png-dir=/opt/libpng --with-xpm-dir=/opt/xpm --with-ttf=/opt/freetype --with-jpeg-dir=/opt/jpeg-6 Any information is appreciated.
