Supervisor silently fails to start/restart (nothing in logs)

I have a fairly basic supervisor config:

[program:drape]
process_name=%(program_name)s_%(process_num)02d
command=python /home/ubuntu/drape/workers/drape.py
numprocs=1
autostart=true
autorestart=true
nocleanup=true
stdout_logfile=/home/ubuntu/supervisord.out.log
stdout_logfile_maxbytes=32MB
stderr_logfile=/home/ubuntu/supervisord.err.log
stderr_logfile_maxbytes=32MB
startsecs=180

I don't think this config actually matters but posting anyway. I'm using the stock supervisor global config. I installed supervisor via standard sudo apt-get -y install supervisor …and just to be sure:

$ sudo apt-get -y install supervisor
Reading package lists... Done
Building dependency tree       
Reading state information... Done
supervisor is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 69 not upgraded.

However, when I try to start supervisor, I get a completely silent failure:

ubuntu@...:~$ sudo service supervisor start
ubuntu@...:~$

There is nothing in the logs (My global config has logfile=/var/log/supervisor/supervisord.log) and there is nothing in the "program logs" either (logfile=/var/log/supervisor/supervisord.log.<stream>.log).

I have a similar provisioning process for other servers that run ruby daemons so to dig in a bit further, I even creating a very simple ruby script and made chmod 777 the thing so there are no permission issues:

$ cat test.rb 
while 1
 puts "hi"
 sleep 1
end
$ ruby test.rb 
hi
hi
hi
...

My question is more of a …"where should I look" question. If supervisor isn't logging anything the only other place I can think to look of is the syslog which doesn't indicate anything crazy to me.
