Ouch! is correct.  That error implies that something is really wrong =
with the version of the jmol.spkg you are using.  That error used to =
occur using an old version of the headless application to server images. =
 Which version is installed?   The installed version is looking for an =
XWindows server.  It shouldn't be, and shouldn't need it.  If you are =
using the properly up-to-date versions this does not occur.  I routinely =
run my sage server on a machine without any GUI inside a screen session =
and do not see this.  Very odd...
