pkgsrc or macports on Mac OS X?

I've used macports for a long time. But recently I'm considering switch to pkgsrc. I thought pkgsrc is for NetBSD only so I just ignore it. But recently I've found out that pkgsrc makes a lot of effort to make its package profile portable accross multiple unices (including Linux, DragonFly BSD, FreeBSD, OpenBSD and Mac OS X）.
