Shibboleth installation and error starting Apache

[rwestmacott]

I installed version shibboleth.x86_64 (ver. 2.6.0-2.1.el6) on Redhat 7.  The installation succeeded but I am not able to start the Apache service.  Our apache version is 2.4.6 The error is:

httpd: Syntax error on line 353 of /etc/httpd/conf/httpd.conf: Syntax error on line 13 of /etc/httpd/conf.d/shib.conf: Cannot load /usr/lib64/shibboleth/mod_shib_22.so into server: /usr/lib64/shibboleth/mod_shib_22.so: undefined symbol: ap_log_error.

Does anyone know of a resolution to this?
