I’m running xubuntu 12.10 and I was able to install the 12.04 binary posted above by first installing this:
launchpad.net/ubuntu/quantal/+p … thon1.46.1
at first a progress par went across in the top right of the ubuntu software center as it was preparing to install and then went away. Don’t be fooled like me by clicking the install button again or it will install it a second time.
nothing seemed to happen for a minute or two but then it actually started the install process.
Cheers
