i don't understand this paragraph.

ah well, it will install there if you don't have any apt-installed
external yet (as this will create the /usr/lib/pd/extra/ path, and deken
can then use it - if run as root).
this is arguably a bug in the Debian package of "puredata".

it will install into the first existing directory it finds where it can
write things to.
if you run as a normal user, you will not be able to write directly into
/usr/ (only root can do that).

yes this is expected. you shouldn't run Pd as root though.

i'm really talking about the "libraries" section, not about the "search
paths".

for many libraries (e.g. "cxc") it doesn't make *any sense* to try to
load the library "/foo/path/to/cxc", as the library is really only a
directory.
the built-in library loader doesn't load paths as library (if you want
that, you must use libdir).
that's why you get errors when trying to load
"/usr/lib/puredata/extra/cxc", as this library simply cannot be loaded
like that.
remove all full paths from your libraries section where you don't have a
file "/full/path/to/${PDLIB}/${PDLIB}.pd_linux"
e.g. there is no "/usr/lib/puredata/extra/cxc/cxc.pd_linux" so you
should remove "/usr/lib/puredata/extra/cxc" from the libraries.
there *is* a "/usr/lib/puredata/extra/zexy/zexy.pd_linux", so you can
keep that.

though shall not blindly add paths and libraries.
in general, you shouldn't add "many" paths and libraries to your setup
anyhow, and instead use [declare].
