</div>Argh, not good :-(<br>

Petr: I've confirmed with Jason that this is fetching from scratch.<br>

</div>Interestingly, here the issue is darcs *get*... what on earth could be<br>
the matter? Jason, could you try running that command by hand? In<br>
other words, doing a darcs get from the tarball?<br></blockquote><div><br></div><div>I don't know what command was being run.</div><div><br></div><div>In the directory where the benchmarking happens:</div><div>$ ls -A</div>
