Did you include func_shell in your Asterisk build?

Fortunately, it's no biggie to build a missing module, because the "make" 
command explicitly keeps track of everything it has already done and does not 
need to do again.  Just cd into the folder with your Asterisk source, run 
`make menuselect` and select "func_shell"  (under dialplan functions).  Then 
run `make` and finally `make install`.
