and here is my etc/apt/source.list :

deb http://ftp.debian.org/debian/ wheezy main contrib non-free
deb-src http://ftp.debian.org/debian/ wheezy main contrib non-free

deb http://ftp.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.debian.org/debian/ wheezy-updates main contrib non-free

deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

deb http://apt.puredata.info/releases stable main



i'm trying to get iem library.
i managed to get it from source but some objects don't work
i'd like to try to get it with apt-get install
i could get ggee and zexy this way and both work properly.
but as said earlier with
$ sudo apt-get install pd-iemlib
i get :
E: Unable to locate package pd-iemlib

so I'm wondering what repository i should add to the source.list
wheezy ? stretch ?
