PHP4 Installation

Hi there, can anybody help me ? I tried to install php4 als Apache Module. I tried to compile it as a static module (./configure --with-apache=../apache_1.3.17) but make on apache returned the following error message: ===> src/modules/php4 gcc -c -I../../os/unix -I../../include -DLINUX=22 -DMOD_SSL=208100 -DUSE_ HSREGEX -DEAPI -DUSE_EXPAT -I../../lib/expat-lite ../../apaci mod_php4.c mod_php4.c:28: zend.h: No such file or directory mod_php4.c:29: php.h: No such file or directory mod_php4.c:30: php_variables.h: No such file or directory mod_php4.c:47: php_ini.h: No such file or directory mod_php4.c:48: php_globals.h: No such file or directory mod_php4.c:49: SAPI.h: No such file or directory mod_php4.c:50: php_main.h: No such file or directory mod_php4.c:52: zend_compile.h: No such file or directory mod_php4.c:53: zend_execute.h: No such file or directory mod_php4.c:54: zend_highlight.h: No such file or directory mod_php4.c:55: zend_indent.h: No such file or directory mod_php4.c:57: ext/standard/php_standard.h: No such file or directory make[4]: *** [mod_php4.o] Error 1 make[3]: *** [all] Error 1 make[2]: *** [subdirs] Error 1 make[2]: Leaving directory `/home/klaessner/config/apache_1.3.17/src' make[1]: *** [build-std] Error 2 make[1]: Leaving directory `/home/klaessner/config/apache_1.3.17' make: *** [build] Error 2 The directories Zend and TRSM exists.
