Well I uninstalled and changed to the ppa version, which comes with debug.

Scratching my head on this one. I created a file that has just the 
phpinfo(); and looking at the debug log I can see that it appears to hit 
the fastcgi (it returns an x-powered-by header) but returns a blank page:

Again...a head scratcher since I've been running nginx and php-fpm for 
years. Perhaps it's worked so well that my memory is foggy from the last 
time I did it.
