No one actually stated the reasons.

Using older piece of code is a problem, why?  Everything in Enterprise
Linux is old.  That is the idea.  Why would this particular piece of 
older code
be an issue and the thousands of other pieces of older code in EL
not be a problem?  I do not understand.  (Out-of-date Firefox drives me

I would think that the paths are hard coded in the package.  So, I would
also think they would behave exactly the same in el5 as el6.  Not "shocking"
at all.  Do the paths somehow float around depending on the revision of
the kernel?  Am I mistaken?  Is there some dependancy statement:

     if el5
        then helper=/usr/lib64/libgksu/gksu-run-helper
     elif el6
         then helper=/usr/lib/libgksu/gksu-run-helper

I would presume the path to gksu-run-helper was simply
hard coded.  What am I missing?

This is from a 64 bit CentOS 5.6 server I also administer.  I had to place
the same link to compensate for the 32 bit path in a 64 bit package.

# uname -a
Linux server.xxx.local 2.6.18-238.9.1.el5 #1 SMP Tue Apr 12 18:10:13 EDT 
2011 x86_64 x86_64 x86_64 GNU/Linux

# rpm -qa *\gksu\*

# ls -al /usr/lib/libgksu
total 44
drwxr-xr-x  2 root root  4096 Dec  5  2009 .
drwxr-xr-x 78 root root 36864 May 10 15:13 ..
lrwxrwxrwx  1 root root    34 Dec  5  2009 gksu-run-helper -> 

So, yes, it reproduces on el5.  Now that is "shocking".  Not really.  :-)
