yep, list-abs is broken too.
today i did a search for all sssad files / folders on my computer and deleted them all. i was quite sure that none of these folders were in pd's search path, but i guess i was wrong.
after deleting all instances of sssad, and then re-installing this new version of pd extended, i was able to make sssad work by renaming the sssad folder, and then setting a path to the new folder name.
then, even easier, i just took all the stuff out of the sssad folder and placed it directly into the extra folder and that also works.
but this is just a temporary fix. maybe we can get the libdir loader fixed?
