configuring new 2.0 install. mb_strtolower

[yuliangr]

i just installed a fresh 2.0 on ubuntu 15.10.    installed several php modules required by the Magento setup.    I verified home page and admin.    I'm trying to setup the cron for indexers.  I edited the crontab file as instructed.     i then chmod u+x magento/bin/magento   and then tried to   ./magento cron:run    

i'm receiving error: 

Fatal error: Uncaught Error: Call to undefined function Magento\Framework\Event\mb_strtolower() in /home/getuncommon/magento/vendor/magento/framework/Event/Manager.php:56

poking around finding some wierd stuff..not sure if expected for ubuntu php7.0 install

>which php
/usr/local/bin/php 

/usr/local/bin# ls -l php*
-rwxr-xr-x 1 root root 27374656 Dec 17 13:26 php
-rwxr-xr-x 1 root root 27208576 Dec 17 13:26 php-cgi
-rwxr-xr-x 1 root root 2149 Dec 17 13:27 php-config
-rwxr-xr-x 1 root root 28071008 Dec 17 13:26 phpdbg
-rwxr-xr-x 1 root root 4522 Dec 17 13:27 phpize

>which php7.0

/usr/bin/php7.0

in /usr/bin....

/usr/bin# ls -l php*
lrwxrwxrwx 1 root root 21 Mar 22 12:02 php -> /etc/alternatives/php
-rwxr-xr-x 1 root root 4410416 Mar 31 12:32 php7.0

/usr/bin/php is a symlink to /etc/alternatives/php    which is a symlink back to /usr/bin/php7.0

so it sounds like when running CLI php, it's using the /usr/local/bin one that does not have mbstring installed.

/usr/local/bin/php -m
