Just out of curiosity, don't you consider homebrew "decent" or do you want official package manager from Apple? (App Store effectively being Apple's solution?)
I use MacPorts which works well enough, but it would be nicer if something comparable came as part of the base system.
Specifically it is annoying that the compiler does not find headers and libraries installed through MacPorts by default. Yes, you can tell the compiler to look for those headers and libraries easily enough. But compared to the experience on, say, Debian, it is slightly annoying.
Having said that, let me point out that I have owned a Mac for ~19 months now, and while my initial plan was to give OS X a quick try, then install Debian, I have not done so.
Also, if somebody has experience with both homebrew and MacPorts, I would appreciate if that someone could tell me about the differences and the respective pros and cons of both.
