probs with stable install

[Terry Davis]

Hello,
I am installing the stable version of horde with php 3.0.18.
Horde seems to work fine.
Imp does not.

1) I am to put php3.ini in /usr/local/lib ...  correct?

if i do that test.php3 says this:
track_vars: No
PHPLIB will not work correctly with track_vars disabled. Enable it in your
config file before continuing.

Here is my track_vars line in /usr/local/lib/php3.ini:
track_vars on           ; enable $HTTP_GET_VARS[], $HTTP_POST_VARS[] and
$HTTP_COOKIE_VARS[] arrays

2) When I go to access IMP i get the following error:
Fatal error: Call to unsupported or undefined function page_open() in
/home/web/htdocs/horde/imp/index.php3 on line 15

I think this is supposed to be included from phplib.  My include_path line
in php3.ini says:
include_path '/usr/local/apache/php:.'                  ; UNIX:
"/path1:/path2"  Windows: "\path1;\path2"

I looked in page.inc and the function is there as it should be of course.

I think this is a very simple something that I am missing.
Thank you for any help.
Terry
