hdri not disabled by --disable-hdri

Hello. I'm trying to build ImageMagick without HDRI support. I have  
ilmbase and openexr installed, but I would like ImageMagick not to  
use them. I'm on Mac OS X 10.4.11 Intel with Xcode 2.4.1 and  
ImageMagick 6.4.1-3. I used ./configure --disable-hdri but lib/ 
ImageMagick-6.4.1/modules-Q16/coders/exr.so is still built and  
depends on libraries installed by ilmbase and openexr. It shouldn't  
do that, right?
