Pd-extended is broken in that it cannot load abstractions that are in
directories which have the same name as the abstraction. At least
that's how I understand the problem. Users of upstream Pd like me

Don't believe google: the official name for [sssad] is [sssad].

Maybe it's the same issue of pd-extended that makes it fail to load
[sssad]? I have no idea.

Can of worms here, you may want to read up in the archives.
Basically it's like this: If your -path setting points to "somedir"
and there is a directory "test" in it like "somedir/test", then you
can load an abstration "myabs.pd" in "test" like this:
This use of directory prefixes as a primitive namespace replacement is
tricky, however. For one, you also have to set the -helppath to
"somedir", if you want to let Pd find the test/myabs-help.pd file in.
This helpfile next to myabs.pd can use [myabs] directly, without
But if you put the helpfile somewhere else, say into /doc/5.reference,
then it won't find [myabs] without directory prefix anymore, so it
has to use [test/myabs]. But if it uses [test/myabs] it won't work
anymore if you copy myabs.pd and myabs-help.pd directly into your
-path or into some other directory with a different name than "test"!
Directory prefixes can make things messy, if you want to just copy
abstractions around, e.g. to make self-contained packages or use
project directories with everthing included.
Pd-extended installs sssad.pd into extra/sssad/sssad.pd and as "extra"
is in your pd-path, you can create [sssad/sssad] in pd-extended as
well as [sssad] - or you used to until something broke. I was never
fond of the additional and redundant "sssad/sssad", but I'm all for
freedom of choice so people may do whatever they like. But the
official name as far as I'm concerned is [sssad].
As a workaround you can move the content of extra/sssad into the
"extra" directory or another directory of your Pd-path.
E.g. if you have a checkout of the Pd subversion trunk in "PDSVN", you
can use this in your .pdrc:
to always load the "trunk" version of sssad.
