I have been having trouble installing the the program pIRS on my os x machine

it says that its dependencies are BOOST and ZLIB

I have installed both but this is still my error

global.h:5: error: ‘boost’ is not a namespace-name
global.h:5: error: expected namespace-name before ‘;’ token

I am unsure how to go about this
