[magick-users] Help! I don't understand delegates. ImageMagick failure on AIX (100% make test errors)

[Rich Cook]

I am still not clear on what you are saying, and my apologies.   
ImageMagick is the only software which does not build and run  
correctly on this filesystem.  I do not get any permissions errors on  
other software, and I've been here about 5 or 6 years now doing this  
kind of thing.  What precisely is ImageMagick trying to do that it is  
not permitted to?
I am going to have to recompile ImageMagick with -g and step through  
the source code, aren't I?  AIX is so slooooowwwww.... bleh.  :-)
