[PD] Can't load iemmatrix lib

[Linux ROUEN Normandie]

Yes-yes, effectively is much better by installing directly 
'pd-iemmatrix' from the system package manager:
iemmatrix 0.3.2
     objects for manipulating 2d-matrices
     (c) 2001-2015 iem
         IOhannes m zmölnig
         Thomas Musil
         Franz Zotter
     compiled Dec  7 2021 : 17:39:48

But it's putting it in '/lib/pd/extra/iemmatrix' and not (I can dream) 
in my default '/home/joe/Pure-Data/externals/iemmatrix' externals path 
(so I have deleted it).
And I have made the necessary changes in my Pd Preferences.

A minor point when opening the [iemmatrix] help it seems that the 
'test.mtx' file (load and save matrices) is missing:
    test.mtx: can't open
    [matrix]: failed to read

Note: There is actually on my Linux Mint 21.3 system two '/extra' 
folders created by either Pd / Pure Data or some externals:
- /usr/lib/pd/extra + 0 files
   /usr/lib/pd/extra/Gem
   /usr/lib/pd/extra/iemmatrix
   /usr/lib/pd/extra/pix_drum
   /usr/lib/pd/extra/pix_fiducialtrack
   /usr/lib/pd/extra/pix_hit
   /usr/lib/pd/extra/pix_mano

- /usr/lib/puredata/extra + 15 files
   /usr/lib/puredata/extra/bob~
   /usr/lib/puredata/extra/bonk~
   /usr/lib/puredata/extra/choice
   /usr/lib/puredata/extra/fiddle~
   /usr/lib/puredata/extra/loop~
   /usr/lib/puredata/extra/lrshift~
   /usr/lib/puredata/extra/pd~
   /usr/lib/puredata/extra/pique
   /usr/lib/puredata/extra/sigmund~
   /usr/lib/puredata/extra/stdout

Why not to have all of 'usr/lib/pd/extra' into '/usr/lib/puredata/extra'?

And of course I'm using my own '/home/joe/Pure-Data/externals' path for 
the externals downloaded thru Deken.

Thanks,
Joseph
