----------- End Snippet ------------

I manually typed in quit at the prompt to make it continue. It would do a few
more operations and would end up presenting me with a prompt again. After a few
of these I killed the emerge.

Reproducible: Always
Steps to Reproduce:
1. USE="-tcltk" emerge scilab
2.
3.

Actual Results:  
During compilation continuously get input prompts

Expected Results:  
Install without user intervention

Created an attachment (id=43294) [edit]
scilab-initialization.patch

Could you try the attached patch? It seems to work here.

While you're at it, could you clean up a bit the dependencies?
I did some tests: to compile against gtk-2, only gtk+-2, libgtkhtml-2
and libzvt are needed. glib-2 can be removed, and gnome-libs-1 should
probably be moved to the gtk-1 only case.
virtual/x11 is also redundant.

Moreover, here scilab does not compile with --without-tk if gtk is not 
installed. So, if someone has -tcltk -gtk, the ebuild should force a default
between them.

In the end, if the default is gtk, RDEPEND should look something like:
RDEPEND="sys-libs/ncurses
	atlas? ( dev-libs/atlas )
	gtk? (
		media-libs/jpeg
		media-libs/libpng
		sys-libs/zlib
		gtk2? ( =x11-libs/gtk+-2*
			=gnome-extra/libgtkhtml-2*
			x11-libs/libzvt
			=gnome-extra/libgtkhtml-2*
		)
		!gtk2? ( =x11-libs/gtk+-1.2*
			 >=gnome-base/gnome-libs-1.4.2
		)
	)
	!gtk? ( >=dev-lang/tk-8.4
		>=dev-lang/tcl-8.4 )
	Xaw3d? ( x11-libs/Xaw3d )"
(or the other way around if tk is default, or maybe print an error and die
in the -gtk -tcltk case?)

grepping through the sources, it seems that libxslt is not needed
(sablotron is used to convert xml to html) so it can be removed from DEPEND.

sci team: can I commit a revision with the cleanup suggested above?

Committed as scilab-3.0-r1.
