	Unfortunately, it's not the case, as the implementation of the
	‘qt’ terminal (as part of the main Gnuplot binary) itself relies
	on QLocalSocket, and thus depends on the Qt libraries.

	So, I'd like to bring back my original suggestion:

	• the ‘gnuplot’ package is no longer transitional, and contains
	  everything from the former ‘gnuplot-x11’ package, except the
	  ‘gnuplot_x11’ driver binary;

	• the ‘gnuplot-nox’ package is no longer built with
	  ‘--without-x’;

	• the new ‘gnuplot-x11’ package only provides the aforementioned
	  driver binary, and depends on either ‘gnuplot’ or
	  ‘gnuplot-nox’ for the main Gnuplot binary.

	FWIW, I've built the packages as described, and put them there:

http://waterlily.siamics.net/~ivan/mini-dinstall/1gray-misc/amd64/
http://waterlily.siamics.net/~ivan/mini-dinstall/1gray-misc/source/

	A brief testing has revealed no new issues, but I'm yet to
	document my changes properly, and still hope that these changes
	could be accepted for Debian Wheezy.

	TIA.

PS.  Actually, there's a thing I haven't tested so far: should gnuplot
	from gnuplot-nox be started with the DISPLAY environment
	variable set, but without gnuplot-x11 installed, it may fail to
	produce a nice error message.
