Oh dear, Nokia and Macports do seem to hate me. I’ve spent half a day to get some version of Qt running on OS X 10.6.2. The problem is as follows. Nokia only provides 32 bit builds of their Qt SDK for OS X (universal binaries for PPC and i386) as can be seen here and here. Under OS X 10.5 this was no problem, since the whole system was basically 32 bit. But Snow Leopard now builds for x86_64 per default. Especially when using Macports. So I thought, lets just install the qt4-mac port from Macports. Wrong again! That port is currently broken. So, my project depends half on Qt and half on stuff from Macports. Now neither one is in a usable state. Ok, so I thought maybe I can force Macports to build in i386 mode only, to be compatible again with Qt. So I edited /opt/local/etc/macports.conf, cleaned the whole Macports tree and reinstalled. Fail again. This time, perl5 fails to build. That port is broken on 10.6 for non 64 bit builds. Hooray. Well, I give up for today, but will continue to investigate and will report back, as soon as either Nokia provides a decent 64 bit build, or Macports recovers and fixes any of their build issues.
