For this reason I generally build gnuplot from source and add the
necessary config stuff to link to libreadline. Steps, roughly, are:
apt-get install libreadline4
apt-get install libreadline4-dev
cd /usr/local/src
apt-get source gnuplot
cd gnuplot-3.7.3/debian
# Edit the file named "rules" and change
--without-gnu-readline
TO
--with-readline=gnu
cd ..
dpkg-buildpackage
cd ..
dpkg -i gnuplot*3.7.3-1*.deb
Then I go into dselect and put a hold on gnuplot so it doesn't get
upgraded automatically during an "apt-get dist-upgrade".
Of course I don't fully understand all the "GPL implications". I
believe what the Debian gnuplot maintainer means is that it's ok to
use GNU readline library with gnuplot, gnuplot just can't be
distributed that way and so (s)he doesn't distribute it that way with
Debian.
