Which guide? I'm assuming it's the one
you wrote?
Also, if you compile with Perl 5.10, you need the runtimes as well or you'll get the Perl 5.10 .dll missing error, if I'm not mistaken. That also needs to be clarified. If you compile with Perl 5.8 (as the ones on the
googlepages one is) you will specifically need to use Perl 5.8 to run it.
And for the record, you can't compile it under 64bit OSes unless you change numerouos things as it was pointed out to me. So if you want to compile it, you need a 32bit OS. If I'm mistaken, this needs to also be noted. And, you have to run the 32bit programs of these files under your 64bit OS because it just won't work.
Lastly, take note that the map files are constantly being updated
here. The ones I downloaded were very out of date, and it might help to get the latest versions. I mean, look at the changelog! The last update was 5/17/2009! It's a huuuge download, so you might want to do it while you sleep or something. With everything included, my Maps folder weighs in at a whopping 3.32 GB! >_<
