undefined method `boolean_label_class=' for SimpleForm:Module?

[Nathaniel Barnes]

Attempting to run migration for my Rails app pixel_paisan is getting an error reading; NoMethodError: undefined method `boolean_label_class=' for SimpleForm:Module.  Gist for the trace at https://gist.github.com/nbarnes/9796454dc28be9792284. Source code for error-production app at https://github.com/nbarnes/pixel_paisan.

I've tried uninstalling and reinstalling simple_form, doesn't help.  Update entire gemset, doesn't help.  Different ruby versions via RVM, doesn't help.  Google doesn't know about my issue.

Does anybody know anything about this? I'm rapidly running out of angles to attack it from.
