I know when I comment out line #66 it just says the next module is garbled:
httpd: Syntax error on line 67 of /etc/apache2/httpd.conf: API module structure `cache_module' in file /usr/lib/apache2/modules/mod_cache.so is garbled - perhaps this is not an Apache module DSO?
and if I comment out line 68 I get:
httpd: Syntax error on line 68 of /etc/apache2/httpd.conf: Cannot load /usr/lib/apache2/modules/mod_mem_cache.so into server: /usr/lib/apache2/modules/mod_mem_cache.so: undefined symbol: apr_atomic_dec
and then I comment out the next one I get:
httpd: Syntax error on line 71 of /etc/apache2/httpd.conf: Cannot load /usr/lib/apache2/modules/mod_ext_filter.so into server: /usr/lib/apache2/modules/mod_ext_filter.so: undefined symbol: apr_poll_socket_add
and so on.
Something is all messed up.
