I mean something more sophisticated, the simple thing having things in the right order is hopefuly already done in pkgng :) I mean more something that is able to go further like resolving some conflicts by changing the ordering automatically, like offerting the ability to depends on provides e.g. depends on http_server instead of depending on apache/lighttpd/nginx/thehttpyouprefer or begin able to depends on feature. An even more. What we have now is really enough to be able to go into a full binary world (and it does really work nicely) but having a real complex sat solver, can help us go forward and imagine an even better package tool. regards, Bapt
