I dont know if there's any clean way to do that, as the ruby gems or deb 
package dependency is managed via apt or gem (the package manager 
itself), other wise you can always two execute statements , one 
beginning of the recipe `gem list > before.gems` and `dpkg 
--get-selections> before.debs`  and one end of the recipe `gem list > 
after.gems` and `dpkg --get-selections> after.debs` and then use a 
report handler to get the diff and process it further.

hope this helps
