prepare failed

[Kuscsik Z. <ku...@gm...>]

I tried the latest cvs version of gnuplot.
I downloaded the source:

  export CVSROOT=:pserver:ano...@gn...:/cvsroot/gnuplot
  cvs login
  cvs -z3 checkout gnuplot


but ./prepare says:

sed -n '/^##trm-files-end/,$p' Makefile.am.in >> Makefile.amt
chmod a-w Makefile.amt
mv Makefile.amt Makefile.am
rm -f Makefile.am Makefile.amt
sed -n '1,/^##plt-files-begin/p' Makefile.am.in > Makefile.amt
echo PLT_FILES = *.plt | fmt | (tr '\012' @; echo ) \
          |sed 's/@$/%/;s/@/ \\@/g;' | tr @% '\012 ' >> Makefile.amt
sed -n '/^##plt-files-end/,$p' Makefile.am.in >> Makefile.amt
chmod a-w Makefile.amt
mv Makefile.amt Makefile.am
automake: configure.in: required file `../config.guess' not found
automake: configure.in: required file `../config.sub' not found

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

Thank you,
