problems configuring PHP

Hi, I am having a problem configuring PHP 4.0.5 for my Red Hat Linux 6.2 server. I am using Apache 1.3.12. When I try to "configure" PHP it comes up with the following error? checking whether to enable a memory limit... no checking whether to enable Zend debugging... no checking for inline... inline Configuring TSRM checking for stdarg.h... (cached) yes Configuring libtool checking build system type... Invalid configuration enable-track-vars': machine enable-track' not recognized checking for ld used by GCC... /usr/bin/ld checking if the linker (/usr/bin/ld) is GNU ld... yes checking for BSD-compatible nm... /usr/bin/nm -B updating cache ./config.cache loading cache ./config.cache within ltconfig ltconfig: you must specify a host type if you use `--no-verify' Try `ltconfig --help' for more information. configure: error: libtool configure failed [root@test php-4.0.5]# I was wondering do I really need this "enable-track" thing. It seems that this is the only one that is causing the problem. If I leave it out would it be better? Thanks. Peter
