Recently built Python 2.5.5 from source on a CentOS 5 box. Now whenever I type an arrow key in the standard Python shell, garbage characters gets printed. This doesn't happen with Python 2.4.

Also IPython shell loads with the following warning message:

WARNING: Readline services not available on this platform.

How to fix this?

Install readline-devel and rebuild.
