New description:
The readline in IPython is broken if ncurses-devel is not installed in
various modern Linux distributions. Installing the ncurses headers from
the distribution (yum install ncurses-devel on Fedora) fixes this.

The problem seems to be that the ancient libtermcap (no new releases since
March 2002) is not enough anymore. I suggest to replace the termcap spkg
with ncurses. Sage-5.9.beta3 builds fine. The only downside is that it
takes ~2mb instead of ~300k, but on the upside the terminal is no longer
broken.
