Comment (by devans@…):

 poppler 0.32.0 was released this morning so I am planning on finishing up
 this ticket over the weekend.

 Question about your patch:

 What the rationale behind these two lines:
 {{{
 configure.env-append    MOCQT4=${qt_bins_dir}/moc
 configure.env-append    MOCQT5=${qt_bins_dir}/moc
 }}}

 The QT4 one doesn't seem to be necessary - haven't tested the other yet.
 Is this just pro forma?
