[PATCH] perf python scripting: Append examples to err msg about audit-libs-python

From: Taeung Song
Date: Tue Feb 09 2016 - 06:53:19 EST


To print the syscall name, the audit-libs-python package
should be required. If not installed, print
the erron string e.g.

# perf script syscall-counts
Install the audit-libs-python package to get syscall names.

But the package name is different in Ubuntu
so append examples the erron string like below.
(similar to a error message of util/trace-event-scripting.c)

# perf script syscall-counts
Install the audit-libs-python package to get syscall names.
For example:
# apt-get install python-audit (Ubuntu)
# yum install audit-libs-python (Fedora)
etc.
