It will be needed a development environment.
First of all one need to open up for the installation of individual program packages in the server-manager panel.
Then it is to choose the right repositories from the server-manager panel.
This will affect also the options that is available from shell.
I went into Linux shell via Putty and installed these packages.
1. Go to the server-manager panel and enable the yum function (program installer)
2. yum install kernel-devel Kernel-headers
3. yum install gcc
4. yum install cvs
5. yum install openssl-devel
I believe this should work for most purposes.
WARNING: HAVING AN DEVELOPMENT ENVIRONMENT INSTALLED WILL GIVE MORE DANGEROUS OPTIONS TO A HACKER THAT MIGHT BE ABLE TO ENTER YOUR SERVER. IT IS UNCLEAR IF THIS ALSO COULD INCREASE THE RISK OF GETTING HACKED.
