Since the LastTests.log file was so large (150K) I extracted a few error blocks from the file. I'm attempting to compile this on a PowerBook G4 (PowerPC architecture) running Ubuntu 12.04.

You told us the OS you are using, but not the platform (e.g., processor). In the build directory of GNU Radio, you can run 'ctest' to see what passes and what fails there. That might help clue us in. Also, you should run volk_profile and make sure that completes without error (that will take some time to complete). Tom
