I did a quick run of configure and I'm not sure if this is a
difference in version of autoconf (mine reports version 2.69), but on
my machine it seems to use the module definition when printing. I see:
"checking for MagickWand >= 7... yes"

I wonder if that might help the situation possibly using the same
prefix for both pkg-config checks?

Thanks,
Karl
