octave development version from source

[Kjetil brinchmann Halvorsen]

I have installed the octave development version from source
(I am updating with
hg pull
hg update
etc ...)

I am on Lubuntu 13.10

octave bombs when trying to show an image:

Here is from upstart:

Gtk-Message: (for origin information, set GTK_DEBUG): failed to
retrieve property `GtkRange::activate-slider' of type `gboolean' from
rc file value "((GString*) 0x1151620)" of type `GString'
Gtk-Message: (for origin information, set GTK_DEBUG): failed to
retrieve property `GtkRange::activate-slider' of type `gboolean' from
rc file value "((GString*) 0x1190720)" of type `GString'

>> B = imread('../LinAlgLibro/baboon.pgm')
warning: your version of GraphicsMagick limits images to 8 bits per pixel

(GraphicsMagic is from installed by synaptic)
> size(B)
ans =

   512   512

>> class(B)
ans = uint8

(so muy image has 8 bits pr pixel)
Now, when doing
imshow(B)

octave bombs!

(A plot window first opens, then immeadiately closes without showing
anything, then bombs!)

What can I do?
