after going back and forth a few times, using "release" instead of "debug" in MSVC i can produce a build only of GEM without an error. i now have a.o. gem.dll. what to do next, just copy & replace in the installed Pd?
(of course i tried already: "gem.dll couldn't load")
btw isn't the imegjpeg plugin also needed for working with .jpg files?
