This came up while I was looking into the problem with blank lines in tool table files.
Two of the sim/axis ini files, profile_axis.ini and random_tc.ini, declare vim as the editor (e.g., "EDITOR = xterm -e vim" and "TOOL_EDITOR = xterm -e vim") but the distribution installs vim as /usr/bin/vi (at least as of the linuxcnc livecd 2.5.0).
If a hapless user tries to edit the tool table via the pulldown file menu in axis he gets a rude popup window with the line "xterm: Can't execvp vim: no such file or directory". Noobies wouldn't know how to respond.
possible fixes:
1) change the ini files to invoke vi or gedit or tooledit as the case may be, or
2) create a symbolic link from /usr/bin/vim to /usr/bin/vi in the distribution
