I'm planning a deployment of scientific software to several users in my lab. The software depends on several libraries that aren't installed by default on OS X. We've settled on macports for providing those dependencies (and have been very impressed with the whole project- kudos!). I would like to deploy our whole package, including macports, as a single installer. Here was my plan. I'd appreciate feedback from any of the devs about whether this will work: As part of the metapackage for deploying our entire software suite, I plan to include the stock macports installer (to add the appropriate receipt to /Library/Receipts), followed by an installer that overwrites the /opt/local tree with the /opt/local tree from our development machine that has all of the dependencies built and activated (all machines are the same OS version and architecture). Will this work or will I hose the macports installation on the target machines? Thanks, Barry
