Problem viewing plots

[Philippe Delavalade]

Hi.

I finally could build sage-10-6 with no MAKEFLAGS set.

Now another problem. This problem is present since release 9 and is not so
important for me being blind but if a sighted people is beside me, I can't
show the graph ; I have to save it and use an image viewer out of sage.

With a command like plot or plot3d like those in the README.md 15.
plot(x^2)
Launched png viewer for Graphics object consisting of 1 graphics primitive
or
plot3d(lambda x, y: x*y, (-1, 1), (-1, 1))
Launched html viewer for Graphics3d Object

I obtain nothing else on the screen.

A friend of mine with the same distribution (slint based on slackware) has
no trouble and he can see the plots.

imagemagick is installed.

I use sage from the console, not from a terminal.

Thanks for advices.
