Hi,

You can visit http://www.percona.com/downloads/percona-toolkit/LATEST/ for downloading latest version of Percona Toolkit. If you don't want to use yum/rpm based installation than you can download binary files (tar.gz) i.e

shell> wget percona.com/get/percona-toolkit.tar.gz

and install it. If you want to install individual tools rather than whole toolkit, you can download and run it like

shell> wget percona.com/get/pt-summary
--2012-09-11 10:22:40-- http://percona.com/get/pt-summary

I specifically do want to use the packages, as I much prefer packages for version management. I'm just trying to understand why the toolkit and xtrabackup have a dependency for MySQL 5.1 instead of 5.5, or why there isn't a version for each.

Here's how I got it to work while still mostly using yum:

# Here are all the currently installed percona packages.

[root@db-2 ~]# rpm -qa | grep -i percona
Percona-Server-server-55-5.5.27-rel28.1.296.rhel6.x86_64
percona-release-0.0-1.x86_64
Percona-Server-shared-55-5.5.27-rel28.1.296.rhel6.x86_64
Percona-Server-client-55-5.5.27-rel28.1.296.rhel6.x86_64

# Try to directly install the toolkit from yum, it errors out with a package overlap.

[root@db-2 ~]# yum install percona-toolkit
