No, I haven't.  Macports scares me.  When I tried them, or fink, in the 
past, they rapidly polluted my boot disk and I didn't have any way to 
unpollute it other than reloading from scratch.

In freebsd, netbsd, or any of the linux distributions, I can trivially 
create a virtual machine in about 20 minutes, screw with it as I like, 
and toss it in seconds.  In modern linux, I can create a root file 
system with btrfs, snapshot, chroot to the snapshot and munge away. 
When I'm done, I can just toss the snapshot.  (Can do snapshots in 
vmware too).

If I screw up my boot drive in MacOsX, I'm in for hours of recovery time 
reloading from Time Machine.  While that's a lot better than it used to 
be now that Time Machine is available, (reloading can now be done 
largely unattended), it's not a price I'm willing to pay in order to 
attempt to use Macports.
