I have installed PDFKit and wkhtmltopdf on my Ubuntu 8.04 server. I am trying to use PDFKit as middleware in my Rails 2.3.8 app and have added the following lines to environment.rb (as directed on the jdpace pdfkit page):
require 'pdfkit' config.middleware.use PDFKit::Middleware
My Mongrel seems to start up but as soon as I request a page the following error appears in the Mongrel log:
** Writing PID file to tmp/pids/mongrel.9270.pid

Has anybody else come across this ?
Any help or suggestions gratefully received !
