I know that this won't help your immediate problem of getting Qt back
but it might help with future problems. You don't really need to
deinstall any package before attempting to rebuild it, e.g.
First create a log file for the task.
script rebuild.log
Now create a backup copy of your current working package, adjust the
version number below to match your system
pkg_create -b qt-3.3.8_11 /tmp/qt-3.3.8_11
Go ahead and build the new binary but don't attempt to install it yet
cd /usr/ports/x11-toolkits/qt33
make clean
make
If you get this far then you've successfully created the binary so go
ahead and install it.
make deinstall reinstall
make clean
If everything goes pear shaped in the install stage and the new version
fails to install then just cd to /tmp and use "pkg_add qt-3.3.8_11.tbz"
to reinstall the previous version.
When everything is finished hit control-D or type exit to stop logging
your output. You have a full record of all output in your rebuild.log
file so if things went wrong during the build you can peruse it at
leisure even after you've closed the window.

It's certainly worth spending some time to familiarise yourself with
portupgrade or portmaster - among other things these do all the
necessary steps of creating temporary backups and reinstalling them if
things go wrong. Portmaster should be adequate for most of your needs,
portupgrade offers more features but at the expense of a bit more
complexity
