Actually it does:

swig -version

Nothing above looks particularly wrong.

If you're still getting the error about missing symbols you still have a
mismatched runtime version.

find / -name libswigpy.so

Then do:
strings /usr/lib64/libswigpy.so | grep SWIG_Python

On the file you find... If there are no SWIG_Python symbols found then
you have 1.3.19 or older... If there are then you have 1.3.20 or
newer... If you have multiple copies of the runtimes installed it can
create the behavior you're seeing.
