I have a page (model: daily_progress_chart) that uses RMagick and
ImageMagick to create a chart using RVG. A few days ago (after some
updates to Rails), this chart stopped working on both my development
machine (MacBook Pro) and the production server (Gentoo Linux). I get
the following error messages. I am totally lost, but I assume that there
is a problem with RMagick. Any ideas anyone?
On the MacBook:
(Note that “parent_of?” is defined and was working fine until I went
to this page. As soon as I try to generate a chart (even a blank one), a
lot of things seem to get disconnected and suddenly instance methods
that were working fine on another page don’t work at all. Also, mongrel
hangs when I try to reboot it, taking over a minute to restart.)
From the development log:

I don’t know if this is a Mongrel problem or an RMagick problem, but it
only happens when I try to make a chart.
Meanwhile, the server output looks like this:

On the Gentoo server, I get an application error immediately when I try
to go to the page that loads RMagick. In the controller I have:
def new
@new_params = { :type_of_chart => “dprs” }
@daily_progress_chart = DailyProgressChart.new(@new_params)
end
daily_progress_chart.rb begins:
require ‘rvg/rvg’
require ‘RMagick’
include Magick
class DailyProgressChart < ActiveRecord::Base
The chart is not generated until save, so I presume the problem is one
of loading the required files. Here is what the production log says:

I have no idea if these are the same problems or different problems. I’m
fairly certain the problem is with RMagick (else why not on any other
page?). Not finding some header files? Something changed? Anyone else
having this problem?
Thanks for any and all help.
