Comment(by ryandesign@…):

 How much memory is in your computer? If you have two processes using 1.5GB
 of real memory each, and you only have, say, 4GB of physical RAM (some RAM
 is needed for the OS and your other apps), your machine will grind to a
 halt as it uses swap instead of RAM. You might mitigate that somewhat by
 interrupting the build (^C) and then retrying it without parallel
 building:
 {{{
 sudo port install gcc44 build.jobs=1
 }}}
