problem installing php-gtk on lucid lynx

I am trying to install php-gtk on ubuntu 10.04 using the post on the ubuntu forums (http://ubuntuforums.org/showthread.php?t=1471531) but i am getting an error message when i try to build php-gtk from cvs

to get php-gtk i use

svn co http://svn.php.net/repository/gtk/php-gtk/trunk php-gtk
cd php-gtk
./buildconf
./configure

this all works fine, but then when i issue the make command i get the message

/home/nick/src/php-gtk/main/phpg_support.c: In function ‘phpg_read_property’:
/home/nick/src/php-gtk/main/phpg_support.c:66: error: too many arguments to function ‘zend_get_std_object_handlers()->read_property’
/home/nick/src/php-gtk/main/phpg_support.c: In function ‘phpg_write_property’:
/home/nick/src/php-gtk/main/phpg_support.c:105: error: too many arguments to function ‘zend_get_std_object_handlers()->write_property’
/home/nick/src/php-gtk/main/phpg_support.c: In function ‘phpg_get_property_ptr_ptr’:

make: *** [main/phpg_support.lo] Error 1

can anyone help me work out what this means or where i have gone wrong?

i am php version 5.3.2-1ubuntu4 (the one that comes with ubuntu 10.04)

i have tried searching the internet and posting on other forums with no luck yet
