Hi Jens - thanks for the report. Nevertheless I think there is something wrong here.
Quite likely. Can you please send an example tree that shows the failure? 'DIST_BUILT_SOURCES' => !! option 'dist-built-sources', Hmm. I had a vague impression that the "no-" was automatically supported, but I'm not seeing it now. or if it could be broken since 314c55f and the test might not work properly for some strange reason? Certainly possible. What am I overlooking? What am I doing wrong? Probably nothing, x 2 :). --thanks again, karl.
