Upgrading Php
 

am try to upgrade php on my server but i get:

checking for Apache 1.x module support via DSO through APXS...

Sorry, I was not able to successfully run APXS. Possible reasons:

1. Perl is not installed;
2. Apache was not compiled with DSO support (--enable-module=so);
3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs
The output of /opt/Apache/bin/apxs follows
./configure: line 3096: /opt/Apache/bin/apxs: No such file or directory
configure: error: Aborting

with a phpinfo i see that the path of apxs is --with-apxs2=/usr/sbin/apxs' , i have try to see if i have any apxs directory in usr/sbin but i dont have it why?
