Error during callback: MLUtils` did not define the expected module `MLUtils`,

Hi, I'm getting this error when loading my package/scripts on linux server using Distributed with multiple cores.

I don't understand why is it happening: check for typos in package module name? I don't see any reference to my code = my mistake.

Thanks for help.
