[Spacewalk-list] spacewalk 1.4-RC cElementTree problem with spacewalk-repo-sync

[Martin Zehetmayer]

Hi,

for I am new on this list let me introduce myself: 
My name is Martin Zehetmayer, I work for as consultant for a small linux solution provider in germany, mostly dealing with RHEL systems. 

I am currently testing spacewalk 1.4-RC6 on a RHEL6.0 x86_64 system. Installing works very fine but when
adding packages to a custom channel I get the following error: 

---
[root at spacewalk ]# spacewalk-repo-sync -u http://10.160.14.83/cobbler/ks_mirror/testrepo -c testchannel1-x86_64 -t yum
Traceback (most recent call last):

  File "/usr/lib/python2.6/site-packages/spacewalk/satellite_tools/repo_plugins/yum_src.py", line 25, in <module>
    import cElementTree
ImportError: No module named cElementTree

After searching I found a post in this list from Michael Calmer which reports the same error under SLES. As mentioned above I tested it under RHEL6 and the same problem appear. It can be solved using three tests as suggested from Michael. 

Here is a diff of my changed yum_src.py:
