Fixed problem whereby scons would try to install the headers before compiling the libraries, even when not requesting an install. This was solved by moving ./include to the front of CPPPATH (otherwise scons would think it should be picking up headers from $INSTALL_HEADER_DIR if that  was also on the include path - it would then install the headers there before compilation). Also fixed boost version check to work for boost 1.33.1, added stricter error checking to the compilation and fixed some library checks so they work at image engine too.
