Unable to determine correct path for gitolite scripts from the authkeys file.

Perhaps you haven't installed gitolite yet?

Or perhaps this is an HTTP mode install?  If so, please set the GL_BINDIR
environment variable to the full path of the gitolite scripts, then re-try
this command.  For example (if you followed doc/http-backend.mkd precisely):

    GL_BINDIR=/var/www/gitolite-home/bin $0 $@

EOF2
    exit 1

# for normal repos, the GL_BYPASS_UPDATE_HOOK above suffices, and in fact you
# don't even need this program.  But for the gitolite-admin repo, the
# post-update hook will also get called, which then needs these:
export GL_RC
export GL_BINDIR
export GL_ADMINDIR
