Trouble building CM 10.2 from source --logcat attached--

[mlin]

Hello, I have been trying to build CM 10.2 from source as a way to start familiarizing myself with Android development. Unfortunately, on each of my builds the camera is broken (though camcorder works). I am running a Ubuntu 12.10 virtual machine on my mac book air with 4th gen i7 processor. I have tried the following things to fix: use proprietary blobs from external source instead of those pulled from my phone, different versions of 64 bit Ubuntu from scratch, rebuilding my android development environment. As you may be able to see, I thought something was going wrong with the build or extraction process so I thought it was a problem with my setup. Anyhow, nothing I've done has resolved the issue. Here is what I believe to be the critical portion of the logcat showing the camera crashing AFTER I try to take a pic. I have looked through the logcat but with my limited knowledge I can't devise a solution to the problem.
