I am using 4.2.1.alpha0 which built fine and all tests passed o n64-
bit ubuntu. Here's an example of the message:
{{{

sage: E = EllipticCurve('14a1')
sage: E.isogeny_graph()
sh: kpsewhich: not found
sh: kpsewhich: not found
Graph on 6 vertices
}}}
Is this caused by this system not having some graphics thing installed
(which I expect that it doesn't)? The normal behaviour would be to
opo up a window with a picture in it. However,
{{{
sage: t = E.isogeny_graph()
sage: t
Graph on 6 vertices
sage: t.show()
}}}
produces no error message (and no picture either).
