As far as I can tell, Hoe by itself doesn’t have anything available to  
facilitate the creation of gems that contain C extensions. Of the gems  
that I have installed which do have extensions, none of them seem to  
also use hoe, so I don’t really have any examples to go by. Any  
suggestions for best practice when doing this sort of thing?

Hoe just sits on top of rake and generates your gemspec (and a bunch  
of tasks). There isn’t really anything for hoe to do for extensions  
(tho suggestions are welcome). So, almost the same way you’d do it via  
a plain gem:

Hoe.new(‘blah’, Blah::VERSION) do |p|  
p.spec\_extras[:extensions] = [“extconf.rb”] # or whatever style  
extension  
end
