Depends on what you consider "easier".  If you install readline, but
don't want to rebuild Python, you could also try installing the
rlwrap program and then invoking Python with that:

  bash$ rlwrap python

which should intercept the inputs and handle them with some nice
readline capabilities.

Otherwise, just make sure that Python builds with readline support as
you've read elsewhere.

-tkc

PS: and you mention being on CentOS but running apt-get.  I believe
CentOS and other Red-Hat based distros use "yum" instead of "apt-get"
