It seems two .sgml files are missing (and this prevents the docs from building):
tsm-system-rows.sgml, and
tsm-system-time.sgml
openjade:contrib.sgml:145:1:E: cannot find "tsm-system-rows.sgml"; tried "tsm-system-rows.sgml",
"./tsm-system-rows.sgml",
"./tsm-system-rows.sgml", "/usr/share/sgml/tsm-system-rows.sgml", "/usr/share/xml/tsm-system-rows.sgml"
openjade:contrib.sgml:146:1:E: cannot find "tsm-system-time.sgml"; tried "tsm-system-time.sgml",
"./tsm-system-time.sgml",
"./tsm-system-time.sgml", "/usr/share/sgml/tsm-system-time.sgml", "/usr/share/xml/tsm-system-time.sgml"
thanks,
