[GEM-dev] [pix_image] backend 'magick' unavailable on Linux

Sat Feb 20 18:18:58 CET 2016

It's strange. The pd-deken's <gem_image*> files are broken. [pix_image]
works properly after replacing broken deken's(~/pd-externals/Gem) folder
with pd-extended's(/usr/lib/pd-extended/Gem). It must be checked?

best,
jonghyun
