Error: Could not find tools necessary to compile a package

Hi,

I am getting an error while installing the package RNeo4j. It pops up that there are other build tools need to be installed. But all the tolls mentioned in the url are installed in my MAC.

Downloading GitHub repo nicolewhite/Rneo4j@master
'/usr/bin/git' clone --depth 1 --no-hardlinks --recurse-submodules https://github.com/neo-technology/neokit.git /var/folders/72/d89g6kdj7sd48kl2wy_dp9600000gp/T//RtmpaLNr8L/remotesca06fdb8ba6/nicolewhite-RNeo4j-eea1ac1/neokit

Could you please let me know if I missed any steps ?

Thanks!
