Manually and inefficiently. It helps that turnover is low. At least now the process is documented. Two years ago it was trial and error. All the dependencies take a while to compile, but we've done it enough times now and have the operations written down precisely enough that aside from some data indexing tasks that have to run overnight (and which aren't strictly necessary to get started developing) we can set up a new environment in about 3 hours. Next step is probably a bash script to automate most of the process on each of our 2-3 most commonly used platforms.
