Sorry, but asking how to install MySQL on Mac OS X is absolutely nothing to do with Perl whatsoever. You might as well ask "what's the best computer to buy" because you use Perl on it, or "what kind of music do you listen to", because you're using Perl to write a cd database. And how on earth did your post get frontpaged? The section is called seekers of Perl wisdom, not seekers of MySQL wisdom.

update: I just noticed it's not on the front page anymore.
