Which dependency solver were you using? I'm assuming it wasn't internal, which should be removed in this version. I think you're probably running afoul of the RESOLVE_ALTERNATIVES setting, which for the apt resolver default to 0. That is, all alternative build dependencies will be stripped out. You should be able to confirm this by looking at the dependencies in the dependency package--they should be printed as part of the build log. You should see the filtered dependencies as having all the alternatives removed. On the Debian buildds, RESOLVE_ALTERNATIVES is always 0, except for the experimental and backports buildds which use aptitude and are out of necessity more flexible, but less reproducible. For all stable/testing/unstable builds, alternative build dependencies are not allowed. I'm not sure what Ubuntu buildds do. I hope that helps explain things. If my assuption is wrong, I'll be happy to look at it further. Regards, Roger -- .''`.
