I have installed Zimbra Collaboration Suite 5.0 RC 1 on fedora 7 and it looks to have installed fine. But the zmapachectl does not run and the spell is stopped. When I start the zamapachectl manually, I get the error

"syntax error on line 232 of /opt/zimbra/conf/httpd.conf: cannot load /opt/zimbra/httpd-2.2.4/modules/libphp5.so into server: /opt/zimbra/httpd-2.2.4/modules/libphp5.so: cannot restore segment prot after reloc: permission denied"

What could be causing the problem.

Please help.
