That would be OK. I think the right thing to do is to patch build-systems that are aware of prefixes to understand Debian's python schemes. Either in Debian or upstream, as appropriate. We want to preserve the property that things install to /usr/local by default, and to /usr only by explicit request. That's what I've pursued, so far. Maybe the right thing to do is to change the sysconfig.get_path API (#1041778) to select a scheme for you. But I'm hesitant about that approach. It would probably fix a number of these build systems in one stroke, but it's a little more magic. Stefano -- Stefano Rivera http://tumbleweed.org.za/ +1 415 683 3272
