I got errr when I run server cups start after yum update

[Mike Zang]

I used yum to update my FC4 server yesterday, then I found my cups server doesn't work after this updating.

When I tried service cups start, some message as below:
[root at server1 ~]# service cups start
Starting cups: /usr/bin/python: error while loading shared libraries: libpython2.4.so.1.0: cannot open shared object file: Permission denied
cupsd: error while loading shared libraries: libz.so.1: cannot open shared object file: Permission denied
[FAILED]

Does anyone help me?
