See here: http://sage.ucsc.edu/~wgscott/xtal/wiki/index.php/Snow_Leopard_upgrade_notes#Previously_updating_X11.app_to_2.4.0_in_10.5_created_problems The "dirty fix" mentioned got X11 working again. By: Daniel Bond GSL::graph [ reply ]   2009-09-22 05:01 Hi all!! I've been fighting a problem for a couple of hours. I cannot call GSL::graph. I get the following errors: libplot: ignoring request to create plotter of unknown type graph: error: couldn't open graphing device The installation previously worked but I'm not sure what broke it. For reference I'm using ruby 1.8.6, plotutils @2.5_0, and gsl @1.12_0. Thanks for any help you may give.
