unable to resolve type 'uint32_t'

I'm running OS X mavericks. I'm installing from the latest source - although I had to modify the gem spec to remove the reference to ["lib/ropencv/ropencv_types.rb","lib/ropencv/ropencv_ruby.rb"] or it wouldn't build.

Installing works ok, but when I try to include OpenCV I get the following error:

Thank you for reporting the issue.
It was already solved on master but never released as gem. I pushed a new gem for rbind and ropencv.

Thanks! I was using master of ropencv but not rbind.

Thanks for a great gem.
