yum install lynx
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib64/python2.4/lib-dynload/binascii.so: failed to map segment from shared object: Cannot allocate memory

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Dec 11 2006, 11:39:03)
[GCC 4.1.1 20061130 (Red Hat 4.1.1-43)]

If you cannot solve this problem yourself, please go to
