I need to install python 2.4 on a fedora 3 system. I followed the instructions in
http://www.python.org/download/releases/2.4/rpms/
i have the following contents in /etc/yum.repos.d/python24.repo

[python24]
name=Fedora Core 3 - $basearch - Python 2.4
baseurl=http://www.python.org/ftp/python/2.4/rpms/fedora-3/
enabled=1
gpgcheck=1

further following the instructions, rpm --import http://www.python.org/ftp/python/2.4/rpms/KRUD-GPG-KEY gave me:
error: http://www.python.org/ftp/python/2.4/rpms/KRUD-GPG-KEY: import read failed.

after a lot of search i found the above command to be replaced by
rpm --import /usr/share/rhn/RPM-GPG-KEY
rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora
at http://forums.fedoraforum.org/archive/index.php/t-94931.html

after this, when i run yum install python 2.4, it gives me the following error:

ImportError: librpm-4.3.so: cannot open shared object file: No such file or directory

anybody pls tell me what can be done?? I am a project trainee and new to such stuffs, so veterans out there, pls help me...
