How to install Ipython on multi-version Python ?

Hi,

I use Centos 6 x86_64 which come with python 2.6.6. Since I want to try a new python version, I already installed python 3.3 from source and put it in /opt/python3. So right now if I type "python" in a shell it come with python 2.6.6, and if I type "python3" it come with python 3.3.

I want to know how's the way to install IPhyton for both installed python version??

since "yum install ipython" will automatically installed Ipython for python 2..6.6

Thanks,

MBT
