Problem:
httpd: Syntax error on line 117 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/mod_auth_mysql.so into server: dlopen(/usr/libexec/apache2/mod_auth_mysql.so, 10): Symbol not found: _ap_pstrcat\n Referenced from: /usr/libexec/apache2/mod_auth_mysql.so\n Expected in: dynamic lookup\n
Solution:
Replace the line that says "#define STRCAT ap_pstrcat" with "#define STRCAT apr_pstrcat"
