Problem installing binary MacPorts 1.7.1

[James Reese]

I'm using an iMac running OS X 10.5.6. When I run the MacPorts 1.7.1  
installer, it gets to the step of "Finishing Installation" and never  
completes. There is no apparent disk activity and no apparent comm  
actvitity. I have to force kill it to get it to exit.

I've tried completely removing MacPorts using the instructions on the  
wiki and rebooting the machine before trying the installation. In  
every case I get to the same spot in the installation process and no  
further.

Any help will be greatly appreciated.
