I recently installed a debian etch-based Linux OS. The etch gretl version is
1.6.0. However, it is pretty straightforward to compile 1.6.5. One thing I
noticed is that the configuration script was not consistent. ./configure
returned a dependency error (libxml), so I installed libxml-dev. ./configure
then displayed no issues, but make had errors associated with the lack of
libxml2-dev (I believe).
