# Builds the dependencies needed for compiling Blender 2.53 on RHEL 6
#
# The process this script uses is:
# a) Firstly, use yum to install a list of packages known to be needed,
#    and which are available in the RHEL 6 repositories
#
# b) Then download the source RPMS for other needed packages, using ones known
#    to work.  (From Fedora 13 mostly, and a few from Fedora 12)
#
# c) Compile and install these downloaded SRPMS, in an order known to work ok
#    (tested on my boxes)
#
#   Reference URL where the initial list of packages was gotten from, then modified
#   to suit RHEL 6:
#     http://wiki.blender.org/index.php/Dev:2.5/Doc/Building_Blender/Linux/Fedora_12/CMake
#
# NOTE - You'll need to run this script with sudo (preferred) or as root, as it needs to
#        install packages.  Please inspect this script before running it, and change
#        anything you need.  At least the Fedora mirror server variable, and probably
#        the temp directory.  Maybe even the compilation flags too. :)
