Is there any reason QuickCheck specifically requires containers >= 0.5? Perhaps its lower bound could be relaxed.<br><br><div class="gmail_quote">On Wed, Jul 18, 2012 at 11:29 AM, Ross Paterson <span dir="ltr"><<a href="mailto:ross@soi.city.ac.uk" target="_blank">ross@soi.city.ac.uk</a>></span> wrote:<br>

</div>I'm talking about unattended automated builds, so tweaking isn't an<br>

</div>Actually --force-reinstalls does work in this case, and this thread began<br>
with Levent being unhappy with the failure option for his package, so<br>
I'm tempted to use that flag on all hackage builds.<br>
