Pessoal, estou tentando instalar o apache + svn no meu ubuntu, seguindo esse tutorial: http://www.ronaldorigoni.com.br/instalar-subversion-e-apache-ubuntu/

ele me retorna esse erro:

ERROR: Module cgid does not exist!
It looks like you've deleted /etc/apache2/mods-available/cgid.load, so mod_cgid cannot be enabled.  To fix this, please purge and reinstall apache2.2-common.
