Problem installing PHP/pdflib on Debian

Hello - I'm trying to install the following software on Debian 2.2: MySQL Apache PHP pdflib tiff lib jpeg lib pspell aspell (required by pspell) I wrote a shell script to automate this (listed below). The script runs fine on RedHat 6.2, but the PHP ./configure step gives the following error messages: <snip> checking whether to include Pdflib 3.x support... /usr/local yes checking for libz needed by pdflib 3.x... already zlib support checking for jpeg_read_header in -ljpeg... no no checking for png_create_info_struct in -lpng... no no checking for TIFFOpen in -ltiff... no no checking for PDF_show_boxed in -lpdf... no no configure: error: pdflib extension requires pdflib 3.x. Please tell me what I'm doing wrong. Thanks - Jim #### script begins #### MySQL cd /usr/local/src groupadd mysqlgrp useradd -c mysqladm -M -s /bin/false -G mysqlgrp mysqladm cd /usr/local/src tar -xvzf /usr/local/src/mysql-3.22.32.tar.gz cd /usr/local/src/mysql-3.22.32 ./configure --prefix=/usr/local/mysql --with-named-curses-libs=/lib/libncurses.so.5.0 make make install scripts/mysql_install_db chown -R mysqladm.mysqlgrp /usr/local/mysql/var chmod -R go+rwx /usr/local/mysql/var starting MySQL #### Apache cd /usr/local/src tar -xvzf /usr/local/src/apache_1.3.14.tar.gz cd /usr/local/src/apache_1.3.14 ./configure --prefix=/usr/local/apache #### tiff lib cd /usr/local/src tar -xvzf /usr/local/src/tiff-v3.5.5.tar.gz cd /usr/local/src/tiff-v3.5.5 ./configure --noninteractive make make install #### jpeg lib cd /usr/local/src tar -xvzf /usr/local/src/jpegsrc.v6b.tar.gz cd /usr/local/src/jpeg-6b ./configure make make test make install #### pdflib cd /usr/local/src tar -xvzf /usr/local/src/pdflib-3.02.tar.gz cd /usr/local/src/pdflib-3.02 ./configure --enable-shared --enable-shared-pdflib make make test make install ldconfig #### pspell cd /usr/local/src tar -xvzf /usr/local/src/pspell-.11.2.tar.gz cd /usr/local/src/pspell-.11.2 ./configure make make install #### aspell cd /usr/local/src tar -xvzf /usr/local/src/aspell-.32.6.tar.gz cd /usr/local/src/aspell-.32.6 ./configure make make install #### pspell continued cd /usr/local/src/pspell-.11.2/modules ./add-modules cd .. make make install #### PHP cd /usr/local/src tar -xvzf /usr/local/src/php-4.0.3pl1.tar.gz cd /usr/local/src/php-4.0.3pl1 ./configure \ --with-mysql=/usr/local/mysql \ --with-apache=/usr/local/src/apache_1.3.14 \ --with-config-file-path=/www/config \ --enable-track-vars \ --with-pdflib=/usr/local \ --with-pspell=/usr/local
