These packages represent two old versions of CrossOver that Codeweavers has since consolidated into a single product. There are 6 open bugs against these packages and they use the old python eclass. In addition, supporting the latest version requires an entirely new ebuild and a new license in the tree. I have sent an email to gentoo-dev@ about the license change. I have also written an ebuild for the latest version, 12.1.2. It should resolve most if not all of the outstanding bugs in the app-emulation/crossover-office-bin and app-emulation/crossover-office-pro-bin packages. I plan to commit it with myself as maintainer after the new license enters the tree. With that in mind, is it okay if I mask the old versions for treecleaning? I will go ahead with this in 7 days (as per chithead's suggestion) if there is no response.
the bugs you've marked as blocker aren't actually bugs. they're improvement requests. the existing ebuilds are for binary packages that people have purchased.
