That's really odd - I thought (based on what it looks like) that 'Xdialog' was one of the old guard; the Athena Toolkit or something like that. Bleh. :(

On the other hand, modifying it to use none of those libraries, at least for the dialog end, is trivial: change 'Xdialog' to 'dialog', remove the 'xterm -e' line from the 'vi' invocation, and launch the whole script as 'xterm -e pmedit'.
