Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> JRUBY_HOME=/usr/share/jruby jruby -S rake compile
> /usr/share/jruby/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:55:in `require':
> It seems your ruby installation is missing psych (for YAML output).
> To eliminate this warning, please install libyaml and reinstall your ruby.
> rake aborted!
> LoadError: no such file to load -- psych
> /<<PKGBUILDDIR>>/Rakefile:1:in `(root)'
> /<<PKGBUILDDIR>>/Rakefile:14:in `block in (root)'
> (See full trace by running task with --trace)
> make[1]: *** [debian/rules:12: override_dh_auto_build-indep] Error 1

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
