[csw-users] php: missing hash?

[Gerard Henry]

hello all,
i'm trying to deploy a symfony project with opencsw packages of apache 
and php.
But i got an error:
PHP Fatal error:  Call to undefined function 
Sensio\Bundle\DistributionBundle\Configurator\Step\hash()

and this error seems to be that hash is missing in php. If i understand, 
hash is now part of php since > 5.1.2:
http://php.net/manual/en/function.hash.php

and with a little test:
PHP Fatal error:  Call to undefined function hash() in 
/opt/csw/apache2/share/htdocs/titi.php on line 2

echo titi.php:
<?php
echo hash('ripemd160', 'The quick brown fox jumped over the lazy dog.');
?>

if i look at phpinfo(), i see:
'--enable-hash=shared'
'--with-mhash=shared,/opt/csw'

and:
# /opt/csw/php5/bin/php -m |grep hash
#

anybody can tell if i 'm wrong?

thanks in advance for help
