Whebevr I try to start Apache 2.2 I get the following error:

Code:
httpd: Syntax error on line 111 of /usr/local/apache2/conf/httpd.conf: API module structure `php5_module' in file /usr/local/apache2/modules/libphp5.so is garbled - perhaps this is not an Apache module DSO?

At line 111 I have :

Code:
LoadModule php5_module modules/libphp5.so
"uname -a" returns this :
SunOS myserver 5.9 Generic_117171-07 sun4u sparc SUNW,Ultra-80


Does any kno how to interpret the error?
