xset [-display display] +fp $XVIEWHOME/lib/X11/fonts/xview/misc

does not add the open look fonts to your X11 server?  All X11R4 compatible
servers should have these loaded in the default locations...

I imagine you might be able to get it to work, but you'll need to create
bitmaps from each font object first.  The xv_set() command for the cursor
can take an X11 bitmap as the object.  We'll have to look into building
that into the library.

the xv_find command can be used to determine whether or not a font is
available.  The O'Reilly book has an example for the case of fonts.
