Exception when installing the new DVD built with the latest rpm on IA64

[Zhang, Yanmin]

I built up new CD with the latest rpms on my IA64 tiger machine, but I failed
to install it on IA64. anaconda reported an exception. See below log.

********************End of log*******************************

The exception happened when anaconda tried to install libgcc-4.1.1-28,
the first rpm.

I checked /usr/lib/python2.4/site-packages/yum/yumRepo.py and found
__headersListFromDict is defined in class YumRepository.

In file usr/lib/anaconda/yuminstall.py, 
class AnacondaYumRepo has below new comments/code:

    #XXX: FIXME duplicated from YumRepository due to namespacing
    def __get(self, url=None, relative=None, local=None, start=None, end=None,

__get calls __headersListFromDict.

Why modified it?
