Turns out, this prevents tools like install-info being built. Now trying to build devel/gettext I can't get it installed, as it always wants to install info files using install-info, which of course fails. How do I tell the system not to build info files (or manpages or all of the stuff above I don't want in the first place) when building ports? I've tried with "make -DWITHOUT_INFO install" as well as with putting WITHOUT_INFO=yes in make.conf. Gettext will still fail to install. Is this a gettext problem? Or a generic ports problem? I'm running current on arm (thanks again to freebsd-arm people for fixing it): FreeBSD dreamplug 10.0-ALPHA1 FreeBSD 10.0-ALPHA1 #15 r255499M: It's also not possible to "make index" for INDEX-10 if you use a stripped-down ports tree (none of the language ports), as there are some dependencies in the tree to french (cad-astk) and russian (stardict-*) which obviously can't be resolved. Help is appreciated! Cheers, Mat
