Sorry for my delayed reply.  Let's say you want to build a 4-way
universal MINC that works on 10.4 and 10.5.  You do the following:

For CMake: Very easy.  Just set the following settings:
CMAKE_OSX_ARCHITECTURES   i386;x86_64;ppc;ppc64
CMAKE_OSX_SYSROOT         /Developer/SDKs/MacOSX10.4u.sdk
CMAKE_CXX_FLAGS           -mmacosx-version-min=10.4
CMAKE_C_FLAGS             -mmacosx-version-min=10.4

For configure/make:
You basically just need to add "-mmacosx-version-min=10.4 -isysroot /
Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -arch ppc64 -arch
x86_64" to CFLAGS and CXXFLAGS.
