In the meantime I got around the problem by copying the build from berlin,
so I also cannot reproduce the failed build. Apparently some machine did
correctly compute the derivation; if there is not an obvious error somewhere,
it might be easier to close the bug report as not reproducible or non-deter-
ministic.
