Comment:
Don't know tbh. It is mentioned as a runtime dependency along with `setuptools` in [setup.py](https://github.com/derrod/legendary/blob/e6bb6/setup.py#L40), which does seem wrong as readme mentions:
>Requirements
    PyPI packages: requests, **optionally setuptools and wheel for setup/building**

Perhaps `wheel` is only relevant for installation through `pip` from PyPi, which supports `wheel` format.
