I am following instruction on php-gtk website to install it on my machine and every time I try run the buildconf I get this error. Can not figure it out why. Any idea why?
Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
rebuilding aclocal.m4
rebuilding configure
