Transforms works when included in dependencies, but not in devDependencies or otherDependencies

Hello there,

Thanks a lot for this awesome projects.
I've been scratching my head around this: It seems that all browserify transforms (babelify, cssy, rollupify, etc.) are found by browserify in the module compilation when included in package.json dependencies, but not in devDependencies or in otherDependencies. Is there a way to make wzrd.in works when transforms are declared as such in package.json?
