[Cdash] upgrade to 1.6.2 failures

[thehighhat]

Running 1.4.1 for many months successfully.  currently on rhel 5.3.

Tried to upgrade to 1.6.2 using the wiki instructions and the zip file.

Visited the CDash page... nothing displays.

Confirmed httpd and mysqld running.

Looking at logs.. found httpd errors:

Call-time pass-by-reference has been deprecated - argument passed by
value;  If you would like to pass it by reference, modify the
declaration of [runtime function name]().  If you would like to enable
call-time pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI file.  However,
future versions may not support this any longer.  in

Thoughts?
