other choices you have are build from source, or try to use
Macports/Fink/Homebrew/easy_install/pip/buildout-recipe/<your-favorite-solution-here>.
Those all rely on source builds as well, they're just hiding the details.
Which makes things way more confusing when something goes wrong.

About Macports specifically, I haven't tried in a few years but certainly
don't remember things always working out of the box. And AFAIK Homebrew is a
replacement for Macports for many people because the latter was issues.
