I am happy to report that

    (a)  my hard drive hasn't crashed yet, and that Disk Utility says 
S.M.A.R.T. status is "verified" (though I will run some tests on the drive).

    (b) I found a backed-up copy of /usr/include/mach/machine.h, deleted 
the garbled file and replaced it with the backup. I then ran "sudo port 
clean nspr" followed by "sudo port -d install nspr" -- and the 
installation completed without any hiccups.

I'm now going to try resuming the installation of gnome-control-center. 
Wish me luck, and thanks for your help!
