Precisely.  I have the same problem, as does anyone contemplating
fixing a confusing test.

If you make changes to darcs, you absolutely should not rely on the
buildbot, as the buildbot network is very incomplete.  It's possible
that your machine happens to be identical to a buildbot in every
respect, but it's definitely not certain (e.g. which version of
libcurl you have installed, whether you also have haskeline installed,
or libwww, or curses-dev, etc).  Also because changes only hit the
buildbot after I've run the tests and pushed them, which means you're
adding to my workload when tests fail.
