Our automated repository checks [1] have detected that the 'klondike' repository contains ebuilds that trigger fatal errors during the cache regeneration. This usually means that the ebuilds call 'die' in global scope indicating serious issues or have other serious QA violations. Global-scope failures prevent the ebuild not only from being installed but also from being properly processed by the Package Manager. Since metadata can not be obtained for those ebuilds, no cache entries are created for them and the Package Manager needs to retry running them every time it stumbles upon them. This involves both a serious slowdown and repeating error output while performing dependency resolution. The most common cause of global-scope failures is use of removed or banned APIs in old ebuilds. In particular, this includes eclasses being removed or removing support for old EAPIs. Nonetheless there are also other issues such as performing illegal operations in global scope (external program calls), malformed bash in ebuilds or malformed metadata.xml. The error log for the repository can be found at: https://qa-reports.gentoo.org/output/repos/klondike.html In particular, please look for highlighted error messages. Please fix the issue ASAP, possibly via removing unmaintained, old ebuilds. We reserve the right to remove the repository from our list if we do not receive any reply within 4 weeks.

This is going to be harder to fix. Breezy is reported as a valid alternative to bzr but I haven't tested it well and we don't have it on the tree.
Well I took the easy route here, I migrated the repository to git using breezy and changed the ebuild to use git instead. I also found many of the other -9999 ebuilds still used git instead of https so I have fixed that too :) Reopen the bug if needed.
