Ubuntu is a gnome-centric distro. I'm not surprised they built it with

Read the ebuild:
less $PORTDIR/app-office/lyx/lyx-1.5.4.ebuild
and you will see:
RDEPEND="$(qt4_min_version 4.1.1)
x11-libs/libXrandr
x11-libs/libXcursor
x11-libs/libXrender
...
The call to qt_min_version is upsetting equery, which just reads the
literal strings and doesn't know to execute that call to find the real
dep
