Vagrant setup for testing R packages with clang and UBSAN

apt-get update

# Install packages needed to build R
apt-get install -y vim g++ gfortran make libreadline-dev
apt-get install -y clang-3.4 lldb-3.4 llvm-3.4-runtime 

# ====== Set locale ======

# The image doesn't set LC_TIME, LC_NUMERIC etc, which causes warnings when 
# starting R
echo "LC_ALL=\"en_US.UTF-8\"" >> /etc/default/locale

# ====== Install TeXLive ======
# This will result in a more compact install than installing the needed Ubuntu
# packages which results in >1GB download. 

cd /tmp

# Download and extract texlive

# ====== Build and install R ======
