I've been using debian testing on my office pc for over ten years and I've never run into insurmountable problems.} b) You may try to build the newest version of gretl (1.9.8, released yesterday). You'll find detailed instructions in appendx C of the User's Guide, but here's a summary. First, install gretl's build dependencies: the list should be, more or less, debhelper (>= 7.0.0), libgtk2.0-dev, libglib2.0-dev, libreadline-dev, zlib1g-dev, libxml2-dev, gnuplot (>= 4.2), gnuplot-x11 (>= 4.2), libgmp-dev, libaudiofile-dev, libesd0-dev, libfreetype6-dev, libpng-dev, libblas-dev, liblapack-dev, libxslt1-dev, libmpfr-dev, libfftw3-dev, texlive-base, texlive-latex-base, gfortran, r-base-dev, unixodbc-dev, libgtksourceview2.0-dev It is very possible that installing all those packages is done automagically for you by the command apt-get build-dep gretl but since you're using debian stable, there is some small chance that some requisites were added in the meantime (I don'have time to check now) It won't hurt to uninstall the existing verison of gretl, just in case any conflicts arise. Then, you download the source from http://prdownloads.sourceforge.net/gretl/gretl-1.9.8.tar.bz2 and untar it in a directory of your choice. From a shell, navigate to there and issue the commands ./configure --enable-build-doc --enable-quiet-build --prefix=/usr/ make sudo make install This will give you the latest and greatest; the only possible drawback is that some of the -dev packages are too old to compile 1.9.8 c) Combine a and b (that is, do a first, then b). This is almost certain to work.
