The master branch does not support Ubuntu Lucid (10.04) any more: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MinimumSoftwareVersions
However, the tooledit documentation in master still talks about special steps needed to work with Lucid: http://linuxcnc.org/docs/devel/html/gui/tooledit.html#columnsorting
Those docs should be updated to not talk about Lucid workarounds any more.
