Consistent error in installing ppaquette-gym-doom

[shubhoghosal]

Hello Philip,
I tried installing this package on both MacOS (High Sierra) and Windows 7, with both Python 2.7 and 3.6 (Anaconda in both environments, also tried WinPython on Win7). I am consistently getting the same error with the install of doom_py. Error below.
Tried both a direct pip install and gym-pull. Gym-pull is itself giving an issue with Python 2.7.
Is there anything you can suggest as an alternative or to troubleshoot? I am doing this for an AI course and this has me completely stalled.
Sorry for the bother and thanks!

Could not build doom-py: Command '['make', '-j', '7']' returned non-zero exit status 2. (HINT: are you sure cmake is installed? You might also be missing a library. doom_py requires boost, boost-python, sdl2 on OSX (installable via 'brew install boost boost-python sdl2')

Would like to add that the prereqs in the HINT section are already installed
