Umm, sorry for possible cross-thread, I did search and thought I'd come up with a suitable existing thread to post to but seems its not in right area. Never mind, Using notes here http://www.howtoforge.com/perfect-server-centos-6.4-x86_64-apache2-dovecot-ispconfig-3-p4 it seems that the source given for mod_ruby has disappeared. http://fossies.org/unix/www/apache_httpd_modules/mod_ruby-1.3.0.tar.gz seems to have gone. http://ftp.riken.go.jp/pub/FreeBSD/distfiles/ruby/mod_ruby-1.3.0.tar.gz is still currently working HTH
