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
