imagemagick and gem-plugin-magick, but it still can't load. how to solve it?

Ubuntu 14.04-3 x64
Pd-0.46-7 self compiled
GEM: ver: 0.93.3 / GEM: compiled: Aug  8 2013 / from Pd-Deken

mail archive attached.

thanks,
jonghyun

Thanks for the additional information.

The log contains:

verbose(6): backend 'magick' unavailable

As far as I can tell, this means it detected ImageMagick plugin, but
couldn't proceed - I don't know why, and the code is a maze of twisty
plugin factories that I don't yet understand.  Maybe one of the GEM devs
can help you debug this - it might be a problem with how it is packaged in
Deken, or a missing library dependency on your system, or something else.

Sorry, and good luck,


Claude
