Nice! But on Fedora there's only ufsparse library (as of now, anyway) and SuiteSparse has to be installed by hand :( As for email not making it to the list.. I think it's because whoever maintains this list forgot to set reply-to header. To work around this, just use "Reply All" and (optionally) delete the user's email, leaving the list email only. _______________________________________________ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
