The httpd RPM should Require elinks, since /usr/sbin/apachectl runs "links -dump" to access status reports. The httpd spec currently isn't requiring elinks, so things like /etc/init.d/httpd fullstatus won't always work
I think it would be a overkill to enforce a package dependency for this rather obscure feature; better to just print "elinks package missing" if ! test -x /usr/bin/links. (especially since server-status isn't enabled in the default httpd.conf)
If links isn't installed, you can always telnet to the port and dump the output ;)
This was fixed in 2.0.40-17, thanks for the report.
