Hi Brendon, it's an interesting problem. I could reproduce it on a fresh Ubuntu 16.04 install (which I was about to setup for myself anyway). It turns out that for that case a virtual font within a virtual font is to be used, which PyX didn't support yet. Adding it was surprisingly easy, please find by fix in changeset 3678. This resolves the issue for me, it probably does so for you as well.
