ok gotcha---

when I'm building VIPS from source--- what's the flag I need to use to
compile openslide support?

Also I have started to use OpenSlide to help me do the transcoding of files


./configure --with-tiff-include=/usr/local/include

is what I used when I configured vips with the latest libtiff....   I am
guessing just add a  --with-openslide-libraries or something as well and
point to the right spot?
