The test snapshots really shouldn't be used to make Debian packages. They should use a proper make export build.
Yeah, that's what I'm trying to say too. But aren't http://pike.ida.liu.se/generated/pikefarm/packages/7.6/latest and http://pike.ida.liu.se/generated/pikefarm/packages/7.7/latest made the same and proper way, just from perhaps-not-stable source? If so they should be good enough for the experimental dist.
