stap error

[manjunath k]

Hi,

 I've setup systemtap and the following error is seen after executing the
hello world example.
stap -ve 'probe begin { log("hello world") exit () }'

PASS 1: pased user script and 0 library scripts in 0usr/0sys/...
semantic error: unresolved arity-1 function: identifier 'log' at <input>:1:15
semantic error: unresolved arity-0 function: identifier 'exit' at <input>:1:28
