First step after deciding a port is a must is to go into the port and make config to set things up the way you want. Then run make missing and pkg add as much as possible (this to avoid excessive compiling). Finally pkg lock everything you had to build because you changed it. > It's loss of control which is the problem.

You do need to keep the ports and packages you use in reasonably close sync - ideally use the ports tree the packages are built from. So when you upgrade packages also upgrade the ports tree and rebuild the ports. There is a script called sync-ports which pulls the right ports tree - although the version I have doesn't handle 10.2. The only time life gets nasty is if you have to customise a dependency and something else can't live with that customisation. I've not hit that yet, so far all my needed customisations have been on high level packages. -- Steve O'Hara-Smith <steve@sohara.org>
