Started a GNOME 2.9 build today. Here's the bit of business I had to overcome.

The evolution-data-server build was crapping out because it couldn't find "nspr.h," a file from Mozilla's Network Security Services. It was properly checking in the configure stage, and properly not finding it, but the appropriate compile flag wasn't being set for some reason, so the build died.

(On Luis' tinderbox it seems to be correctly not finding in and therefore not trying to use it.)

Solution: "--enable-nss=no" added to my jhbuild configure script. My 2.9 build rolls on.
