there are NO repos for 6.5
The out of date mirrors are no more ( well there might be 2 or 3 that have not been deleted yet)
if you run these on 6.5 you will get an error of "unable to connect to mirror"
yum install gcc
yum install pygame
for those to work on 6.5 you have to edit ( manually) the files in "/etc/yum.repos.d " to point the repos to "The VAULT"
( the historical archive )
also if you try to install "gcc" by ONLY!!!! installing ONLY "gcc" you will have major problems
Things like packageconfig and automake will be missing
on cent you have to install the development group
yum groupinstall "Development Tools" "Development Librarys"
double check the spelling from the output of
" yum grouplist "
