I can see the docstrings on readthedocs.

PyForecastTools is excluded from pysat's requirements on RTD so that's how this came about. Used to be that Fortran stuff didn't work. Glad it does now, I didn't remember that it was Fortran when discussing it earlier.

It's not fortran, so I am not sure how it ended up on that list to begin with. In any case, problem now solved!
