TensorFlow (GPU) libcudart.so.7.5 error -- cannot open shared object file

Question

Installing TensorFlow with GPU on Ubuntu 14.04. Fairly new to the Ubuntu/UNIX environment so lots of things I don't get. When searching this issue, I came across instances of being unable to import CUDA 7.0 when they have CUDA 7.5 installed (since TensorFlow doesn't support 7.5). I have CUDA 7.0 installed, but it seems to be looking for 7.5 - why is this? I have in my .bashrc file the following lines:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda-7.0/lib64"
export CUDA_HOME=/usr/local/cuda-7.0

But I'm still seeing the issue below... Anyone have any advice?

>>> import tensorflow as tf

You need to install tensorflow from SOURCE to configure the settings. Installing by pip or easy_install will not work.

I have the same problem after upgrading tensorflow from 0.6.0 to 0.7.1 using pip.
