Mongrel (web Server) - Deprecation

Deprecation

After the original author Zed Shaw left the Ruby on Rails-scene the releases of Mongrel stopped. The current release 1.1.5 is no longer able to install in Ruby versions higher than 1.9.2 which is recommended for Rails 3, the fix is to use the much older 1.2.0-pre2 release of Mongrel which isn't stable.

A new and maintained server, called Thin, uses the Mongrel parser.
