Is there any chance that the CGIT_CONFIG environment variable is defined
differently for the two invocations?  If it is not defined then CGit
will default to a built-in location (by default /etc/cgitrc).

I have never tried using a CustomLog like that, but with a default
logging setup I do see CGit errors in /var/log/apache2/error_log.
