After having installed the iPhone SDK 3.1.2, Interface Builder is not in sync with Xcode anymore. The light indicator at the bottom of the XIB window is grey. IB doesn't see any files from the Xcode project. Xcode is always open when I start IB.

I tried rebooting. No luck.
I tried removing the preferences files for Xcode/IB. No luck.
I tried reinstalling Xcode/IB. Still no luck.

This page explains how IB monitors the changes in Xcode. While it was an interesting read, it didn't provide any help about how to investigate my problem.

Any help would be appreciated.

EDIT
Here's additional information. I enabled the debug logs for launchd, and I noticed the following line that appears every time Interface Builder is started:

[0x0-0x1b01b].com.apple.InterfaceBuilder3[315]: Couldn't open shared capabilities memory GSCapabilities (No such file or directory)

This really seems to be related to my issue.
