Someone mentioned caffeine, but sometimes the command line is more
useful, especially if you run your port commands from a script.
While “pmset noidle” is running the machine is not supposed to go to
sleep. So you could structure your port script along the lines of

#!/bin/bash
pmset noidle &
... do the work here ...
kill %pmset

You can also use pmset to manipulate the power management settings,
bypassing the System Preferences. See the man page for details.
