Can't get ImageMagick to process uploaded images using paperclip

Question

When I upload images I am getting the following error:

[paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /tmp/stream20091218-7204-1fuv2j1-0 is not recognized by the 'identify' command.>

I have staging servers that have been setup on VMs that work fine, but once I move out to the production server this is what I get. All servers are running on Archlinux, although the staging servers are on 64bit OS's while the production is an a 32bit.

If I run:

identify -version

I get an error until I add the /usr/local/bin to the PATH, to which I will then see the ImageMagick specs. Unfortunately, altering the PATH doesn't seem to have any effect when uploading files directly to the server.

I have also been unsucessful when setting the location paperlclip looks for the image lib via:

config.after_initialize do
  Paperclip.options[:command_path] = '/usr/local/bin/'
end

Any clues on how to configure things to allow imagemagick to process the images?

Thanks for the help.

It turned out that the png and jpeg delegates weren't available when compiling the IM. After downloading and installing the delegates, then re-compiling IM things are now working.
