Description of problem:
On a fresh fc5 system, updating hplip will trigger an update of hpijs
but will not trigger an update of cups-libs though it should
Because /usr/lib/python2.4/site-packages/cupsext.so refers to symbol
cupsLangDefault which is defined in updated cups-libs while it was not 
in original (not updated ) fc5 

Version-Release number of selected component (if applicable):
             |  fc5 original|           fc5 updated
-------------+--------------+-----------------------
hplip        |  0.9.8-6     |           1-6.6a-1.1
hpijs        |  0.9.8.6     |           1-6.6a-1.1
cups-libs    |  1.1.23-30.2 |           1.2.3-1.6


How reproducible:
always

Steps to Reproduce:
1.fresh fc5 install 
2.yum update hplip
3. /etc/init.d/hplip restart
4. (alternative)  hp-clean 
  
Actual results:
Traceback (most recent call last):
  File "/usr/bin/hp-clean", line 35, in ?
    from base import device, utils, maint
  File "/usr/share/hplip/base/device.py", line 39, in ?
    from prnt import pcl, ldl, cups
  File "/usr/share/hplip/prnt/cups.py", line 27, in ?
    import cupsext
ImportError: /usr/lib/python2.4/site-packages/cupsext.so: undefined symbol:
cupsLangDefault


Expected results:
should at least start !!! :-)

Additional info:
For original cups-libs (cups-libs-1.1.23-30.2.i386.rpm)
    $ ls -l /usr/lib/libcups.so.2
      -rwxr-xr-x 1 root root 132708 Feb 11  2006 /usr/lib/libcups.so.2
    $ readelf -s /usr/lib/libcups.so.2  | grep cupsLangDefault
    $ # no output
      
For updated cups-libs ( 178298 Sep 15 03:04 cups-libs-1.2.3-1.6.i386.rpm)
    $ ls -l /usr/lib/libcups.so.2
      -rwxr-xr-x 1 root root 218184 Sep 13 18:30 usr/lib/libcups.so.2
    $ readelf -s /usr/lib/libcups.so.2  | grep cupsLangDefault
      79: 0001dd80    69 FUNC    GLOBAL DEFAULT   10 cupsLangDefault
IMHO since updated libcups.so.2 exports 143 new global function symbols (almost
2x more) compared to the 156 of the original, it should get a different major
version number.
