It would be useful to know your experience.

Before trying to make a Neo Geo game, do you have experience in making game on any other platform ? Or even experience in making apps ? Or even programming at school or university ?

I would not recommend Neo Geo platform for dev beginners, as it can be very frustrating. Making a game is very hard, you need to master programming, game design, graphics. With the Neo Geo you also have to master the limitations of the hardware. That's a lot of things.

If you successed to install a C compiler, just go and don't try to be always up to date with the lastest groovy library. Just keep things simple, try to display your first sprite and have fun.
