I confirm the build failure on 10.6/64bit.
The reason is now clear: There were two problems with this linker line:

The first one are missing libraries like "-lz". This problem comes from 
qt4-mac and is fixed in the latest qt4-mac package. Alan still got it 
because a 3rd-party qmake binary was interfering.

The second problem is the extra "-arch i386", which leads to failure on 
x86_64. It comes from the qtpfsgui-mac package itself: In its 
project.pro file, it has the edifying lines:

      # Is this next line strictly necessary? gcc should compile for the 
correct architecture by default.
      CONFIG += x86

This line is responsible for the spurious "-arch i386" flag, and it is 
indeed not necessary. If one comments it out, the package builds on 
10.6/64bit. It also still builds on 10.5/32bit/intel.
