You can open a Moba Local Terminal and enter MobApt. This will start the package manager where you can find all of the packages that are available. I had a similar issues with Python as I needed the python.h file and it was not in my Moba installation. I found it in the python-...-devel pacakge. After installing this package, my Python environment worked flawlessly.

When running MobApt, you can set the check boxes to show or not show things like installed packages or development libraries. I did not notice this at first, so I fumbled around a bit looking for the packages. After setting the right options, I found everything I needed and more.
