If using the port command in a terminal, interrupt by pressing Control-C. (This applies to any command-line program, not just "port".) If using a GUI, consult its documentation. It's important to consider what phase of a port MacPorts is working on, to decide whether interrupting it at that moment is a good idea. Individual ports may deviate, but for a generic port foo:

* Fetch: interrupting ok; resuming will restart incomplete downloads the beginning
* Verify checksums: interrupting ok
* Extract, Patch, Configure: interrupting ok, but clean before trying again
* Build: interrupting ok; resuming should pick up building where it left off
* Destroot: interrupting ok; resuming might not work; if not, remove "$(port workpath foo)/destroot" or clean and try again
* Install: don't interrupt; I don't know exactly what happens
* Activate: don't interrupt; unregistered files might end up getting installed (if you do interrupt, you might have to "sudo port -f activate foo" next time)
* Clean: don't interrupt; files might not get cleaned up (if you do interrupt, run "sudo port clean foo" yourself)
