Comment 7 for bug 362570

yes, there is some kind of conflict.

we have to distinguish between a (manual) python installation going to /usr/local by default and using /usr/local/lib/python2.x/site-packages and the system python using /usr/local/lib/python2.x/dist-packages. IMO it should still be possible to install into the former using the system python. how would you do this? otoh we could just ignore this case and require the locally installed python for installations into /usr/local/lib/python2.x/site-packages. in any case, site-packages should be used for all occasions where prefix is not /usr or /usr/local or when stuff like virtualenv or a userbase installation is wanted.
