[Scribus] does scribus-1.3.3 depend on qt-3.3.x, or will qt-4.x work?

[Jeff Kowalczyk]

I'm about to install scribus on Gentoo Linux ~x86. I'd prefer not to pull
in qt-3.3.6 as a dependency if possible.

[ebuild  NS   ] x11-libs/qt-3.3.6-r1  USE="cups gif ipv6 mysql opengl
postgres sqlite -debug -doc -examples -firebird -immqt -immqt-bc -nas -nis
-odbc -xinerama" 14,224 kB

[ebuild  N    ] app-office/scribus-1.3.3.3 USE="cairo" 11,166 kB

Does scribus actually depend on qt-3.3.x, or will qt-4.x work if built
from source? Thanks.
