I got the 4.9 on my pi2…but at first i was trying with 4.7.
Here is a post that i made when i was having problems compiling @patrikolausson version:

Really no idea about how to make this work with vero2…Maybe there are some things missing or the architecture is different…I dont know 
…@sam_nazarko should be able to clear things up.
