I'm not sure what this "--build=i386" flag is; the way to build a program for a different architecture is to pass "-arch" flags in the CFLAGS, CXXFLAGS and LDFLAGS at configure time:

CFLAGS="-arch i386" CXXFLAGS="-arch i386" LDFLAGS="-arch i386" ./configure

To build a universal binary of cairo in MacPorts, we build for each arch separately and then lipo them together. (So if you just want a universal binary of cairo, you can certainly use MacPorts to get it: "sudo port install cairo +universal".) The reason we switched to using lipo at the time was an endian check in the configure script which the cairo developers at the time did not wish to change:

Cairo has evolved in the five years since then so I don't know what the current situation is when using the simpler method of specifying all -arch flags at once.
