I just wanted to let you know that osgEarth is being masked for removal from Gentoo portage. One of our developers uses Gentoo Linux as his primary development platform and happened to notice it today. From the bug report it looks like they have an inconsistency between OSG and osgEarth versions:
Unfortunately they have chosen to remove the ebuild for it rather than fix the problem since no proxy maintainer is assigned to osgEarth. I thought I would let you know in case anyone in the osgEarth community wants to be a maintainer and help keep it in portage.
