Sorry, I broke Debian tonight.  I am going to load backups so I can recover /usr/local which I destroyed by installing a broken version of gcc that overwrote the working version.  Then I will reboot back into the current version and replace /usr/local with the backed up version.  Sorry this is kind of a screwball process owing to backing up the machine as a disk image.  It should be operational again by about 1AM.
