Rocketfuel build should fail if bzr C extensions not built

[Jonathan Lange]

Since we run the world's most popular Bazaar server, we should be offering our users the fastest possible service. To do this, we need to have C extensions built.

Although we do try to build C extensions (via Bazaar's normal build process), the build succeeds silently if the extensions are not built. Instead, it should fail noisily.

Bug 385453 might be enough to solve this.

Since the move to eggs, I have even less idea how to fix this bug.

Well, we could simply add a check to load the bzr C module and fail with an appropriate error message if it can't be loaded.
