[opensuse-packaging] project "vdr", repository "SLES11 SP3" has empty RPM_BUILD_ROOT?

see $SUBJECT, vdr/dtv-scan-tables fails on SLES11, apparently because RPM_BUILD_ROOT is not set. Of course I could work around this in the spec file, but I find it is a rather strange thing to happen. Can someone enlighten me what the issue is and how to solve it properly? thanks, seife -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org
