Problem with installing php-4.1.2

Hello. I tried to install php-4.1.2 with apache 2.0.35. So, i got both and began to install. configured apache : --enable-module=so to /www then as usual, make and install. all works fine. so began to installing php: configure --with-pgsql --with-apxs=/www/bin/apxs then make got following error messages: sapi_apache.c: In function `apache_php_module_main': sapi_apache.c:81: `NOT_FOUND' undeclared (first use in this function) sapi_apache.c:81: (Each undeclared identifier is reported only once sapi_apache.c:81: for each function it appears in.) make[3]: *** [sapi_apache.lo] Error 1 So, tried to replace the NOT_FOUND in sapi_apache.c this file compiled well after that, but in others appeared many more errors, which broke the compiling process. I think that maybe the the php i trying to compile for apache is too new.. Im using mandrake i dont think that there is anything to do with distribution. or linux. but who knows. maybe im mistaking. sincirely yours. Muxa. beginner in php
