389 server install fail

This is the kind of thing that Microsoft does NOT fail at(as often):

Starting admin server . . .
output: httpd.worker: Syntax error on line 142 of /etc/dirsrv/admin-serv/httpd.conf: Cannot load /usr/lib/httpd/modules/mod_file_cache.so into server: /usr/lib/httpd/modules/mod_file_cache.so: cannot open shared object file: No such file or directory
Could not start the admin server. Error: 256
Failed to create and configure the admin server
Exiting . . .
Log file is '/tmp/setup5R7Gtb.log'

How does this kind of bug happen?
Did they really never QA a new install?
