gitaly-ssh binary is missing
gitaly-ssh binary is needed for project forks to work. I manually copied gitaly-ssh to /usr/bin install directory after "ebuild install" and after "ebuild qmerge" forks are working for me now. I am suggesting to add: "newbin/dobin gitaly-ssh" (for /usr directory) to gitlab-gitaly.ebuild (used last 1.7.1 one).
