The problem is that the Forni *.m files are not found, because they're not in Octave's "load path". When I tested I launched gretl from the directory containing those files. But an alternative is to add a line like the following into the "foreign" block, before calling the "coher" function: addpath("~/stats/octave/forni"); (using the path that's relevant on your system).
