ANd you need to make sure the PATH hits the updated binary and not the 
default other wise you end up with:

/tmp/pbuild/perf recUnknown option: --list-cmds

  Usage: perf [--version] [--help] COMMAND [ARGS]
Unknown option: --list-cmds

It's calling /usr/bin/perf with --list-cmds, versus the perf command I 
am running (/tmp/pbuild/perf). Any way to teach the completion to use 
the perf binary that the user is running?
