yum 설치 관련 질문입니다.

안녕하세요.
yum을 설치 했는데, no module named yum 이라고 나오면서 되지 않네요.
구글링으로 찾아본 몇가지를 해보았지만 똑같아요.
rpm 버전이 문제인것 같기도한데... 어느 rpm 버전이 잘못되었는지 확인을 할 수가 없네요.
도와주세요~

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.2.3 (#1, Feb 2 2005, 12:20:51)
[GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-49)]
