+ Attempt yet again to land the fix for bug 49360 (respecting
+ set-webkit-configuration). We need to handle the cases where
+ trying to run webkit-build-directory to find out where the
+ default configuration might be fails (that shows up on some
+ Chromium bots that apparently don't have perl installed).
