newbie q: Installation problem

Hi, I've a newbie in php. I've downloaded php-4.0.1pl2 but I can't install it on Redhat 2.2.14-5.0. I've reintall my Redhat linux but got the same result. Everytime I type the following commands, it just return as below: ./configure --with-sybase --with-apxs The following msg returns: checking for a BSD compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for working aclocal... missing checking for working autoconf... 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 ... i686-pc-linux-gnu checking for bison... no checking for byacc... no configure: warning: You will need bison if yhou want to regenerate the PHP parsers. checking for gcc...no checking for cc... no configure: error: no acceptable cc found in $PATH Please help. Is there any rpm that I need to install before installing PHP? TIA Emy emytang@411.uptown.com
