apache 2.0.52_3 and mod_php5-5.0.2,1 port config problem

[Leonardo]

Dear all,
 
I'm using FreeBSD 5.1, and now install the apache 2.0.52_3 form the
package and make the mod_php5-5.0.2,1 from the port tree. The whole make
and install is successful, but after I config the httpd.conf to support
the php.
 
I cant start the apache , the error message is:
Syntax Error on line 274 of /usr/local/etc/apache2/httpd.conf:
Cannot load /usr/local/libexec/apache2/libphp5.so into server:
/usr/loca/libexec/apache2/libphp5.so:Undefined symbol "__xuname"
 
The line 274 is:
 
LoadModule php5_module        libexec/apache2/libphp5.so
 
 
And the httpd.conf is same as default.
 
P.S. It's normal if I don't load the php module. How can I solve it?
Please help.
