[isf-wifidog] Delete the default-network

I'm  loaded Apache on my server    OS is Centos 5.5, I have tried twice now
to load it.   When I try to start Apache it fails:

Syntax error on line 206 of /etc/httpd/conf/httpd.conf: cannot
load /usr/lib/httpd/modules/libphp5.so into
server  /usr/lib/httpd/modules/libphp5.so:  undefined sysymbol:
_estrndup

Any ideas ?
