Can you log the value of conf->max_servers?  Also log the value of  
apr_memcache_create?

ie.
ap_log_error(APLOG_MARK, APLOG_INFO, 0, s, "Function: %pp,  
max_servers: %d", apr_memcache_create, conf->max_servers);

from the stack trace it looks like the library isn't being linked in  
correctly, and it's not finding the apr_memcache_create method..  What  
OS are you running this on?
