Apache Server will not run with google authenticator apache module enabled

[baile...@gmail.com]

Hi All

I had google authenticator apache module enabled running on Ubuntu 12.10. I've tried to enable this on Ubuntu 14.04 and when I try to start apache I get this error:

service apache2 restart
* Restarting web server apache2 [fail]
* The apache2 configtest failed.
Output of config test was:
apache2: Syntax error on line 140 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/googleauth.load: Cannot load /usr/lib/apache2/modules/mod_authn_google.so into server: /usr/lib/apache2/modules/mod_authn_google.so: undefined symbol: ap_log_rerror
Action 'configtest' failed.
The Apache error log may have more information.
root@mb-test-01:~# ap_log_rerror

I've got r21 of the module installed.

Does anyone have any ideas?

Cheers

Do you compile the module or just download ?
