To add to Arnaldo's instructions, here's how to get a copy of his tree:

mkdir perf.git
cd perf.git

git init
git add remote acme git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
git remote update

git checkout remotes/acme/perf/core
mkdir /tmp/pbuild
make -C tools/perf  O=/tmp/pbuild
/tmp/pbuild/perf top -z

To try out a different version:
git checkout v3.0
make -C tools/perf

or v3.2, v3.4, etc.

Building perf is fairly quick and you do not have to install them -- 
just run the built binary.
