I have tried this and no success. configure still picks on the system
install of GraphicsMagick and completely ignores the values of
MAGICK_LDFLAGS, MAGICK_LIBS, and MAGICK_CPPFLAGS.

$ env | grep MAGICK
MAGICK_LDFLAGS=-L/home/carandraug/.bin/gm/lib/GraphicsMagick-1.3.14
MAGICK_CPPFLAGS=-I/home/carandraug/.bin/gm/include/GraphicsMagick
MAGICK_LIBS=-lGraphicsMagick++ -lGraphicsMagick

I looked into config.log and and see no mention of those paths, only
of /usr/include/GraphicsMagick
