As far I am concerned MagickWandForPHP 1.0.9 is broken -> fails to compile.
I don't know which version of ImageMagick the devs compiled it against but I tried ImageMagick-6.7.5-7 as well as the allegedly "approved" version 6.3.5-9 as specified in INSTALL (which is wrong since it's < the minimum version required by the compiler!) and version 6.3.8-11
None of these worked since the method MagickSetImageEndian() simply doesn't exist in those versions of ImageMagick.
Unfortunately I can't find a way of contacting the MagickWandForPHP devs, so I guess this will go unfixed.
I reverted to MagickWandForPHP 1.0.8 and it compiles (& works) just fine with 6.7.5-7 (although the compiler reports a lot of deprecated methods and incompatible pointer type warnings).
