Ken,

That looks very promising. I do not want to use the ImageMagick port, mainly because I need to install both IM 6 and IM 7 and there is no IM 7 port. So I would like to do my own manual install of ImageMagick using all the ports from MacPorts.

I think I can resolve what I need for my configure command if you would run

convert -list configure

The send me what it says in the section for CONFIGURE 

or just send me the whole thing.

Thanks.
