it doesn't:

 port variants py26-scipy
py26-scipy has the variants:
   atlas: Use MacPorts ATLAS libraries
   gcc42: Use gcc 4.2 tool chain for building
     * conflicts with gcc43 gcc44 gcc45
   gcc43: Use gcc 4.3 tool chain for building
     * conflicts with gcc42 gcc44 gcc45
[+]gcc44: Use gfortran-mp-4.4 as fortran compiler
     * conflicts with gcc42 gcc43 gcc45
   gcc45: Use gfortran-mp-4.5 as fortran compiler
     * conflicts with gcc42 gcc43 gcc44

... but you probably mean why does it build a gcc at all?

Probably because it requires a fortran compiler to build (http://www.scipy.org/Installing_SciPy/BuildingGeneral) and Xcode doesn't ship with one.
