Several of people (including me) have observed that they sometimes need to do "sudo port install" of many of the dependencies (say, libgcc or perl packages), and that sometimes they need to try multiple times.

But also: can you give a more complete report of exactly what commands you typed and exactly what the error messages were?  "I followed the steps" is actually ambiguous, as you're assuming that we know which steps you followed.   We might be able to guess correctly what you actually did, but if you tell us explicitly then we wouldn't have to guess.
