cgi scripts fail to run from userdir with "End of script output before headers" errors

[Lonni J Friedman]

I definitely have suexec enabled:
[Mon Oct 06 16:09:31.518777 2014] [suexec:notice] [pid 20128] AH01232:
suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

Renaming the suexec binary, and retrying didn't really help:
[Tue Oct 07 16:17:15.854011 2014] [cgi:error] [pid 26631] [client
127.0.0.1:55657] AH01215: (2)No such file or directory: exec of
'/usr/sbin/suexec' failed
[Tue Oct 07 16:17:15.854671 2014] [cgi:error] [pid 26631] [client
127.0.0.1:55657] End of script output before headers: foo.py

I added a handler to the "<Directory /home/*/public_html/cgi-bin>"
section of my apache config, but that didn't have any impact on the
problem.

Any other suggestions?
