Na,

this is possibly not the wrong version of qt but a wrong version of 
gcc. Version 3.0 of gcc (only C++) is binary incompatible to version 
2.96. so a program compiled with g++-3.0 does not link to a lib that 
is compiled with g++-2.96 (like your qt-lib from mandrake). so either 
compile qt2 with the version 3.0 gcc or use gcc-2.96 compiler.

Btw: instead using gcc3.0 take gcc3.2 from Cooker. This is the 
upcomming standard compiler and should be a little bit faster.
