ruby-rrdtool needs ruby-hoe to build (and it has a BUILD_DEPENDS for this) but the installed gem has a dependency on hoe in the gem specification. See /usr/local/lib/ruby/gems/1.8/specifications/RubyRRDtool-0.6.0.gemspec
... s.add_dependency(%q<hoe>, [">= 1.1.1"]) end So currently you must additionally install ruby-hoe to be able to use ruby-rrdtool. Either the gemspec or the pkg dependency need to be fixed. I would prefer to fix the gemspec but I have no idea how to do it. I hope some ruby ports guru knows a good trick and fixes it. thanks -- :wq Claudio
