I finally managed to get PHR running properly on a Raspberry Pi...

In case anyone else is struggling, here is what I did:

- install latest version of Raspbian
- download and compile libboost 1.5.8
- add jessie repository to the apt list
- download and compile libssl 1.0.0
- apt install libminiupnpc10
- copy over files downloaded from phore.io

Not sure if there is an easier way (it seems like there should be), but this worked for me, so I am happy
