Version 0.6.0 of gem2rpm includes all (development and runtime) dependencies for a given Gem. Example: Rack Gem (http://rubygems.org/gems/rack) Version 1.1.0 has no runtime dependencies, but six development dependencies. Console output of gem2rpm --dependencies rack-1.0.1.gem is: rubygem(test-spec) = 0 rubygem(camping) = 0 rubygem(fcgi) = 0 rubygem(memcache-client) = 0 rubygem(mongrel) = 0 rubygem(ruby-openid) = 2.0.0 rubygem(thin) = 0` How can I specify to only include runtime dependencies? I have also opened a ticket on rubyforge.org, but there isn't a lot of activity on that tracker. Thank you for any hints.
