config.log says:

configure:2608: /usr/bin/gcc-4.0 -O2 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -I/opt/local/include -isysroot /Developer/SDKs/MacOSX10.4u.sdk -isysroot /Developer/SDKs/MacOSX10.4u.sdk -L/opt/local/lib -Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -arch i386 -Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk conftest.c  >&5
ld: library not found for -lcrt1.10.5.o

You probably still need to set MACOSX_DEPLOYMENT_TARGET to 10.4. In MacPorts, that's the configure.macosx_deployment_target variable.
