[Rd] Please don't assume a display for package installation

SciViews is the latest of several packages that need an X server to complete package installation.

Please bear in mind that packages may get installed on a server with no display, yet run on client workstations with displays. If your package is intended to start a window when it starts up, please test for a display first (e.g. via capabilities("X11")).

There are ways around this (running Xvfb, arranging a remote display) but they are tedious at best (and few machines come with Xvfb installed).
