Hi, A change in Ruby caused it to hang again, likely due to a pthread semantic difference on kfreebsd. It doesn't hang, neither on Linux nor on FreeBSD. Affected package is the experimental one. It's a pre-release snapshot (candidate RC1) for Ruby 1.9.3, to be released in september, and likely the default Ruby implementation in wheezy. Please see http://redmine.ruby-lang.org/issues/5240 - Lucas
