Can't find my apache error_log folder new Mac (Yosemite) and setting up a new dev environment. At the moment cannot find any error_log folder at the following paths:

/var/log/apache2/error_log
/private/var/log/apache2/error_log
/var/log/httpd/error_log


Any thoughts on where that folder may be?
The location of error_log is defined in /etc/apache2/httpd.conf. Run

grep '^ErrorLog' /etc/apache2/httpd.conf


to see the definition.
