Comment:
I'm attaching a patch; it depends on #4216.
With this patch, if 'convert' is not found, I get an error message like
this:
{{{
/usr/local/share/sage/local/bin/sage-native-execute: 8: convert: not
found
Error: ImageMagick does not appear to be installed. Saving an
animation to a GIF file or displaying an animation requires
ImageMagick, so please install it and try again.
See www.imagemagick.org, for example.
}}}
So the first line is cryptic (but could be useful in debugging, if the
problem is something other than a missing 'convert'), while the rest of
the message is friendlier.
