Remove posix-spawn dependency. posix-spawn relies on a C extension. This does work under JRuby, but it won't work on Travis CI as they disallow JRuby C extensions, as they are considered to not be a good practice. Instead we are using either Process.spawn on Ruby 1.9, or the childprocess gem on Ruby 1.8. childprocess uses native JVM APIs on JRuby, and fork+exec on others. 2012-03-11 10:35:02 +00:00			`require 'childprocess'`
