While I was looking to our spidermonkey ebuilds I noticed we are still carrying this versions that look to be not needed by anything in the tree... maybe they could be removed :) In summary, for slot 0 we only need 1.8.5-r4 ebuild, all the rest in this slot could be cleaned Thanks
There are projects (and people) that still want 1.7, so we will need to keep one of the 1.7's around. But yes the rest can be canned I expect, especially if 1.8.7 is no longer a dependency of any polkit version in the tree.
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
