With Apache, AllowOverride settings are required on the ${INSTDIR}
directory. You can configure this as follows:

# ln -s ${PREFIX}/conf/modules.sample/roundcubemail.conf \
        ${PREFIX}/conf/modules
# apachectl stop
# apachectl start

Create a link into an appropriate part of the web-server's
document root, e.g.:

# ln -s ../roundcubemail /var/www/htdocs

Next, follow ${INSTDIR}/INSTALL or ${INSTDIR}/UPGRADING
