Again, thanks for the help here. wget http://kirrus.co.uk/stuff/pz/wheezy-glibc-sid.sh gives this: and then bash wheezy-glibc-sid.sh gives this: Server OS is not Debian Wheezy. This script must be run on a Debian server, release Wheezy (7). I'm with Creeper Host and don't have access to a control panel or anything - they just provide log in details for PuTTY etc. Looks like CentOS to be honest.
