cant portupgrade qt on 4.10-PRERELEASE box

[Jason]

trying to run portupgrade -ra
and the qt port refuses to upgrade
right now, I have qt-3.0.3_5 installed.
If I portupgrade qt, it tries to upgrade to qt-3.3.1_1
and bombs with 

===>   qt-3.3.1_1 depends on shared library: audio - found
===>   qt-3.3.1_1 depends on shared library: X11.6 - found
===>  Configuring for qt-3.3.1_1

   The specified system/compiler is not supported:

        
/usr/ports/x11-toolkits/qt33/work/qt-x11-free-3.3.1/mkspecs//usr/local/share/qt/mkspecs/freebsd-g++

   Please see the PLATFORMS file for a complete list.

===>  Script "configure" failed unexpectedly.
Please report the problem to kde at FreeBSD.org [maintainer] and attach the
"/usr/ports/x11-toolkits/qt33/work/qt-x11-free-3.3.1/config.log" including
the output of the failure of your make command. Also, it might be a good 
idea
to provide an overview of all packages installed on your system (e.g. an 
`ls
/var/db/pkg`).
*** Error code 1

Stop in /usr/ports/x11-toolkits/qt33.
