I'm trying to install Koha 2.2.9 on an Intel Mac and it's not working. All the pieces work separately (mysql, perl and apache) and the koha install script completed successfully, but I can't see the koha web page on my machine. I'm reasonably sure it's a problem with the apache setup but I don't know where to start. The koha-httpd.conf file is in the correct users directory so apache is seeing it.
