argyllcms-1.8.0 is out with newly supported hardware and bug fixes. Please add to portage. http://www.argyllcms.com/ SRC hasn't changed though I got an error 406 the first time I tried digesting. It worked the second time. I don't know how many of those src_compile and src_install lines from 1.7.0 are still needed.
Added after your reminder in bug #548758 :)
