2 known bugs: . Build doesn't copy libssh* to the destination directory. + workaround is to copy them from the lib directory to destination and recreate links . ssh_config and sshd_config don't install + workaround is to copy them manually Note the software doesn't build to completion until you do the workarounds. Still trying to sort this out, but wanted to get these changes up for more visibility and collaboration.
