interactive terminal in Ubuntu Linux : libreadline5-dev works only in Python 2.6 not 3.1

[Dave]

On Jan 6 I inquired how to "fix" the 3.1.1 interactive terminal
in Ubuntu Linux.   Left arrow yields ^[[D , etc. 

casevh helped by suggesting "libreadline5-dev" be installed.
Did so with Synaptic Package Manager.
The behavior of the Python 3.3.1 terminal is unchanged but
the 2.6.2 terminal is corrected.

Is there any way to fix the 3.1.1 terminal command line ?
