create a file /etc/sbopkg/repos.d/80-slackbuilds-master.repo with this content (one line) slackbuilds master "Official git master from slackbuilds.org" custom git git://slackbuilds.org/slackbuilds.git@master "" then, to have it selected as the default repository, edit the lines of /etc/sbopkg/sbopkg.conf with the variables REPO_BRANCH and REPO_NAME REPO_BRANCH=${REPO_BRANCH:-master} REPO_NAME=${REPO_NAME:-slackbuilds} and do a sbopkg -r (to sync). For temporary usage sbopkg -V slackbuilds/master -r sbopkg -V slackbuilds/master -i my_package_or_queue would do.
