AFAIK this is correct. I have swig 1.3.25 which I installed myself 
because the version in fedora 3 or 4 was not new enough. This version 
complains only about DISOWN, which is not very fatal. The latest gdal 
tarball has wrappers and swig shouldn't be needed. SWIG_NewPointerObj is 
a C macro, which expands to  SWIG_Perl_NewPointerObj which is a function 
defined in the wrapper itself. Is your gdal_wrapper.cpp ok?
