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).
