plotdf renders its display via Openmath (included in Maxima)
which is a Tcl/Tk program. If Xmaxima (user interface) is included
with Maxima, then Openmath should be present. I don't know if
Sage installs Tcl/Tk, maybe you have to do that separately.

It seem likely this is a Unix process exit code which indicates
failure.

FWIW this displays a direction field as expected when I try it
(cvs Maxima + ECL + Linux).
Maybe there is some other way to plot a direction field in Sage.
