Cannot compile phase 2 after recent Roles patch

[Richard Eisenberg]

It looks to me that the problem is caused by an outdated libraries/base repo. Have you run ./sync-all pull? In particular, your libraries/base repo needs to be at ab9e8e3… or later.

Let me know if this was indeed the problem!

Thanks,
Richard
