[Gnuplot-info] I can't ./prepare

[Peder <pe...@ph...>]

I've been trying to install the latest version of Gnuplot on my machine. I
follow the instructions on
http://www.gnuplot.info/development/ethans_instructions.html

Apparently I download the files well enough by:

export CVS_RSH=ssh
export CVSROOT=:pserver:ano...@cv...:/cvsroot/gnuplot
cvs login

cvs -z3 checkout gnuplot

But when I try ./prepare i get the error:

+++++
./prepare: line 17: aclocal: command not found

Some part of the preparation process failed.
Please refer to INSTALL for details.
+++++

Any ideas what the reason could be? Do I have to do something after the download
before the ./prepare ?

Thanks!
