Appears to me that MagickWand for PHP is useless if it's not going to be kept up to date with IM.

the fail in my case was in ImageMagick-6.3.5-2.tar.gz
i think the version is not working properly with MagickWand
i tryed the php4, php5, and both Magickwands, all with errors.
now i have downloaded and installed ImageMagick-6.3.2-9.tar.gz
and works perfect with php4 and php5.
