Rustyll: Incompatibility with CollectionBuilder

[eugestumm]

I tried compiling the sample project from CollectionBuilder-csv, however, Rustyll keeps returning several errors. Here is the project, with a sample data that works perfectly well in Jekyll (https://github.com/CollectionBuilder/collectionbuilder-csv). This is how the error that Rustyll outputs when builds the project.

I formatted the .csv files so they all had all cells filled out, but after that the problem is that Rustyll is not able to build CollectionBuilder.

Please, could you help me with this matter?
