Invalid Apache directory

Hi, I try to build PHP 4.3.4 on AIX 5.1 (It's my first use of PHP). However, it fails in the ./configure step with apache include file: I've tried: ./configure \ --with-apache=/extern/WWW ./configure \ --with-apache=/extern/WWW/ ./configure \ --with-apache=/extern/WWW/include --with-config-file-path=/extern/WWW/conf The message is: configure: error: Invalid Apache directory - unable to find httpd.h under /extern/WWW (or /extern/WWW/ or /extern/WWW/include depending of the option set) However the file exist and is readable: begou@orr: whoami begou begou@orr: ls -l /extern/WWW/include/httpd.h -rw-r--r-- 1 root www 46780 Jul 31 2002 /extern/WWW/include/httpd.h Where is my mistake ?
