urgent,configure-problems

Hello People, I want to configure the version php-4.0.4pl1 on to a RS/6000 with AIX4.3.3. IBM HTTP Server 1.3.12.0, IBM JDK 1.2.2, IBM DB2 UDB 6.1, IBM C-Compiler 3.6.4, LDAP-Server 3.2.0. After unpacking the php-4.0.4pl1.tar-file under /usr/, parallel to the HTTPServer, I used the configure-script as follws: ./configure --with-apache=/usr/HTTPServer/conf/httpd --with-java=/usr/java_dev2 --with-ldap=/usr/ldap --with-ibm-db2=/usr/lpp/db2_06_01 I got the same failure results using only the Apache-parameter: ./configure --with-apache=/usr/HTTPServer/conf/httpd Output: loading cache ./config.cache checking for a BSD compatible install... ./install-sh -c checking whether build environment is sane... yes checking whether make sets ${MAKE}... yes checking for working aclocal... missing checking for working autoconf... missing checking for working automake... missing checking for working autoheader... missing checking for working makeinfo... missing checking whether to enable maintainer-specific portions of Makefiles... no checking host system type... powerpc-ibm-aix4.3.3.0 checking for gawk... no checking for mawk... no checking for nawk... nawk checking for bison... no checking for byacc... no configure: warning: You will need bison if you want to regenerate the PHP parsers. checking for gcc... no checking for cc... no configure: error: no acceptable cc found in $PATH I can't imagine what that means!
