I just used /scripts/easyapache to get rid of mbstring which is a bug in php 4.2.3 and after running it i choose Advanced and did the needful as stated here
but i did not find all the module in the php module mentioned in the above post hence i selected the others as mentioned.
In the end i get an erro sayins SHM_OEPN and hence httpd failed
/usr/local/apache/bin/apachectl restart: httpd not running, trying to start
Syntax error on line 227 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/apache/libexec/mod_throttle.so into server: /usr/local/apache/libexec/mod_throttle.so: undefined symbol: shm_open
/usr/local/apache/bin/apachectl restart: httpd could not be started
