php.ini opened but not readed

Hi.. I write because I did not found a solution to this problem anywhere
else.

I compiled php-4.3.4 and httpd-2.0.48 (Apache) on Solaris 8. I run it in
a chrooted environment (/usr/local/chroot/www/)

The problem I see is that the php.ini file is never readed. It is found,
it is opened and closed, but never readed. Running strace (actually
truss since the OS is Solaris 8) I get this:

open("/apache2/conf/php-apache2handler.ini", O_RDONLY) Err#2 ENOENT
open("./php.ini", O_RDONLY) Err#2 ENOENT
open("/apache2/conf/php.ini", O_RDONLY) = 473
close(473) = 0
open("/etc/services", O_RDONLY) Err#2 ENOENT
stat("/apache2/lib/nss_nis.so.1", 0xFFBEEECC) Err#2 ENOENT

As far as I see that means the file /apache2/conf/php.ini if found,
opened and inmidiatly close. Never read... what do you think could be
the problem? File permission looks OK.

Some other info: that happens using the libphp4, but not the command
line php. truss using the command line php shows this:

open("/apache2/conf/php.ini", O_RDONLY) = 3
pathconf(".", _PC_PATH_MAX) = 1024

read(3, 0x0029E5EC, 8192) = 0
llseek(3, 0, SEEK_CUR) = 38686
close(3)

and the directives are readed.

Any help would be very welcome since I am really lost :-|

Thanks...
