COMP: The Apple GNU compiler/linker has issues with libprog
After the recent upgrade to libproj, the GNU linker reports undefined symbols while building vtklibproj and vtkGeovisCore.
This is apprently a bug in this old GNU compiler/linker. This patch works around the problem by building booth libvtkproj and vtkGeovisCore as static libraries.
This patch has been tested with this compiler: i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)
