If reporting this issue please do so at (not Homebrew/brew or Homebrew/core):

Is there a way a similar patch like that brought up here:
#47
might fix this??

Thank you in advance!

I think you would want to apply this patch:

• https://bitbucket.org/osrf/sdformat/pull-requests/345/fix-os-specific-initialization-in

I will accept pull requests to fix these old formulae, but we aren't maintaining those versions of gazebo/sdformat on homebrew.
