Weird FC16 yum problem

I'm hoping I'm not the first one to encounter this, and unfortunately 
I'm not sure what led up to this, but when I try to use yum, I get this....

[root@wkeen ~]# yum search nano
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

    /usr/lib/python2.7/lib-dynload/selectmodule.so: undefined symbol: mory

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:
2.7.2 (default, Oct 27 2011, 01:36:46)
[GCC 4.6.1 20111003 (Red Hat 4.6.1-10)]

If you cannot solve this problem yourself, please go to
the yum faq at:
