Ok, here's what's happening. Configure attempts to compile a code
snippet it generated as a test for whether Qt is present and works:

gcc prints this message:

and exits with status '1', which configure notices:

Configure prints the text of the failed program:

That program includes code to check the value of QT_VERSION that's
defined in the Qt includes and abort with error code 1 during
compilation if the value is too low:

As we saw above, when configure compiled the program it did abort with
error code 1, so the Qt headers think your Qt version is older than
3.3. 

Have a look around your system and make sure you don't have multiple
versions of Qt installed. Look for multiple copies of
'qglobal.h' (that's where QT_VERSION is defined). You can use 'dpkg
-S /path/to/qglobal.h' to find out what package the specified file is
in, and 'dpkg -l' to ask what version that package is, eg:

craig:~$ dpkg -S /usr/include/qt3/qglobal.h
libqt3-headers: /usr/include/qt3/qglobal.h
craig:~$  dpkg -l libqt3-headers
||/ Name           Version        Description
+++-==============-==============-================
ii  libqt3-headers 3.3.3-7        Qt3 header files

If you really NEED old versions of Qt installed as well, either remove
the -dev packages containing their headers, or explicitly specify which
version to use with the --with-qt-includes argument to configure and/or
by setting your CPATH environment variable.
