All, please note we have moved percona-qa to GitHub:
https://github.com/Percona-QA/percona-qa

To clone it, use:
$ sudo yum install git
$ cd ~
$ git clone https://github.com/Percona-QA/percona-qa.git

reducer.sh was also put directly into this repository (and it is maintained there), so *no* need anymore to separately fetch lp:randgen.
