Testing in Julia v0.6.4 leading to error unsupported?

[EMCP]

Seems I have hit the first block with trying out the code, I am happy to attempt to bring things up to date .. guessing next steps would be to clone the source and tests?

might help to know how to read what the last working version of julia was tested/ approved
