Hello Johannes,

I keep this topic for the list since it is related to purest_json...

Is there a reason that when I try to do :
$ sudo apt install pd-purest-json

apt tries to download :
gem gem-doc gem-extra gem-plugin-gmerlin gem-plugin-lqt
gem-plugin-magick gem-plugin-v4l2 pd-libdir pd-purest-json puredata
puredata-core puredata-doc puredata-extra puredata-gui puredata-utils

I still have installed Pd from source (idem for Gem) ?
Thank you for your clarification.

Jack
