I hope so:

Here it differs because I'm on "qt4-x11-4.6.3" and debian stable. As you
can see above I got these two warnings:

    - Constraint 'libjpeg-dev' is not available, omitting. (This could be a
      virtual package or a bug.)

    - Use of uninitialized value $multiarch in concatenation (.) or string at
      /usr/sbin/embuilddeps line 296.
