Add ‘sass-concat’ to oldie grunt task (in case latest version of main.dev.css — input for oldie.dev.css — isn't created yet, before running oldie grunt task).
Change ‘@include rhythm(property, …)’ to ‘property: rhythm(…); use function instead of mixin. The grunt task ‘pixrem’ takes care of the rem-to-pixel conversions for oldie.
