enabling mbstring on ec2

The error message "Call to undefined function mb_detect_encoding" will
typically result when the "mbstring" extension is not loaded in PHP.


i'm having this error ..usually i go into php.ini and enable some extension on solaris ...now i'm working on amazon ec2 and they have a different php.ini ...i don't see any mbstring extension to enable ..... i read somewhere that you can install in using YUM but not sure i need to do that either...


please disregard i think i found out how to get mbstring happening with yum install

Were you able to install mbstring with yum?
