[SL] Can't start httpd

[<sql...@li...>]

Hi,
I am setting up a new fc4 server to run SL, but am unable to restart httpd
after adding
#SQL-Ledger
Include /etc/httpd/conf/sql-ledger-httpd.conf
to the httpd.conf file.
Before adding the above two lines, I could see the apache test page. After
adding these two lines, I stopped httpd and then restart it, but the httpd
won't start.
Any idea?
GL
