php/osx and firebird

[James <jtu@xxxxxxxxxxxxx>]

I've attempted to access a firebird database living on an 
osx/apache/php machine.

When I'm running the following script,
<?php

	ini_set("magic_quotes_sybase", "On");

	$host = 
'localhost:/Library/Frameworks/Firebird.framework/Resources/examples/employee.fdb';
	$username = "sysdba";
	$password = "masterkey";



	$dbh = ibase_connect($host, $username, $password);

	if (!($dbh=ibase_connect($host, 'sysdba', 'yourpass', 
'ISO8859_1', 0, 1)))
  		die('Could not connect: ' .  ibase_errmsg());

	$stmt = 'SELECT * FROM employee';
	$sth = ibase_query($dbh, $stmt);
	while ($row = ibase_fetch_object($sth)) {
	 echo $row->full_name, "\n";
	}
	ibase_free_result($sth);
	ibase_close($dbh);
	  
?>

I get the following error:
"Call to undefined function ibase_connect()"


How do I enable those functions?  I've looked at the php 
documentation (http://uk2.php.net/manual/en/ref.ibase.php )

"To enable InterBase support configure PHP --with-interbase[=DIR], 
where DIR is the InterBase base install directory, which defaults to 
/usr/interbase."
I've tried to add:
--with-interbase=/Library/Frameworks/Firebird.framework/Resources
to my php.ini and it didn't work.

Am I pointing to the wrong directory?  What other configuration/setup 
do I have to do to enable php's interbase functions?

Thanks.
