Page build failure from Github importer

Hi,

The Github importer initially reports success, but the page build fails. I tried this from my own account, and a colleague of mine tried it from his. Both page builds failed.

Earlier today I used the importer for the workshop template and that worked fine, so I don't think it's an importer issue. Here's the error message:

The page build failed for the `gh-pages` branch with the following error:

Page build failed. For more information, see https://help.github.com/articles/troubleshooting-github-pages-builds/.
