trying out xaraya 2.x: installing categories module

I am testing the xaraya 2.x branch and have a problem when trying to 
install xarpages.

I have set block list compiler to BL1 in baseconfig.
I have taken xarpages for xaraya 2.x from http://www.it-works.ch

xarpages depends on categories module

If i use the categories module from mtn i get this when i install 
categories:

Fatal error: Class 'Dynamic_Property' not found in 
/var/www/html/modules/categories/xarproperties/Dynamic_Categories_Property.php 
on line 21

If i try the categories module for xaraya 2.x from 
http://www.it-works.ch i get:

PHPException
PHPException [2] was raised (native)
