Migrations fail due to bitmask method call in model

[polarblau]

The new repo doesn’t allow issues, so I'll post this here for reference.

As long as I have the bitmask call in my user model, my migrations will fail with

rake aborted!
Could not find table 'users'

Here's the stack trace

A workaround is to comment the bitmask reference out, run the migrations, then put it back.
