I needed to install rmagick over the weekend as I was playing with the file_column plugin. Rubygems has usually been good to me so I didn’t expect any problems when I issued the command: #gem install rmagick <snip> /usr/lib/ruby/gems/1.8/gems/rmagick-1.15.5/./lib/rvg/misc.rb:321:in `get_type_metrics': unable to read font `/usr/share/fonts/default/TrueType/verdana.ttf' (Magick::ImageMagickError)
