Getting an error when installing one of the Caffe dependents: Boost

I'm getting into machine leaing, and I recently happened upon this: Wide-Area Image Geolocalization with Aerial Reference Imagery .

It's a net that predicts the GPS location of an image, from just the image. Needless to say, I was thrilled, only to discover that one of the requirements:

import caffe
import numpy as np
import multiprocessing
import matplotlib.pyplot as plt
from collections import defaultdict

was Caffe, which I can't seem to install, because I can't install the main prerequisite: Boost

I first tried to run the standard sudo apt-get install libboost-all-dev, which not only failed:

The following packages have unmet dependencies:

It gave me a "but it is not going to be installed" error. I then tried to install from source:

wget -O boost_1_55_0.tar.gz http://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz/download
tar xzvf boost_1_55_0.tar.gz
cd boost_1_55_0/
./bootstrap.sh --prefix=/usr/local
./b2

And that promptly filled up my entire terminal with g++ errors. I then tried to start from scratch:

sudo apt-get --purge remove libboost-all-dev libboost-dev libboost-doc
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get clean
sudo apt-get update
sudo apt-get install libboost1.54-dev

And while that worked with the test script: https://stackoverflow.com/questions/12578499/how-to-install-boost-on-ubuntu

When I tried then to make caffe, I got this:

CXX src/caffe/util/db.cpp
In file included from ./include/caffe/common.hpp:19:0,
                 from ./include/caffe/util/db.hpp:6,
                 from src/caffe/util/db.cpp:1:
./include/caffe/util/device_alteate.hpp:34:23: fatal error: cublas_v2.h: No such file or directory

                       ^
compilation terminated.
make: *** [.build_release/src/caffe/util/db.o] Error 1

What could be causing this error?
