# Add and build the all of the required Julia packages. In order to allow the use of
# BinDeps.jl we need to temporarily install additional system packages.
#
# - BinDeps.jl runtime requirements: sudo, make, gcc, unzip, bzip2, xz, unzip
#
#   BinDeps runtime requirements are only used while other packages are being built which
#   makes them safe to only be temporarily installed. When installing system libraries 
#   BinDeps always uses "sudo" to install system packages and waits for user confirmation
#   before installing a package. We'll both install "sudo" and always supply the `-y` flag
#   to ensure that BinDeps installations work automatically. A good test to make sure
#   BinDeps is setup correctly is to run `Pkg.add("Cairo"); Pkg.test("Cairo")`
#
# - HDF5.jl requires the EPEL repo to install hdf5 automatically through BinDeps
#   (https://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/)
# - yum-config-manager is installed by: yum-utils
