Guest Additons Installation Failure on Oracle Linux 6.4

[mschreib_il]

I am new to the world of Virtual Box. I am running 4.2.18 on Windows 7/64 bit.

I have been able to create a virtual box with Oracle Linux 6.4; installation of Guest Additions is failing because I do not have "make" and "gcc" installed. However, I am unable to understand why "make" and "gcc" are not installed since the packages clearly appear in the installation media and since I thought I installed them manually as follows:

% rpm -iUF ./Packages/gcc-4.4.7-3.el6.x86_64.rpm
% rpm -iUF ./Packages/make-3.81-20.el6.x86_64.rpm

-both commands returned immediately without error, so I am assuming that they worked (should there have been some time delay before the OS prompt returned?).

-related question: given that at this point in the current build of my virtual linux machine, I have no capability for ftp'ing or downloading files from the external world, how would I supply packages which are missing from my installation?

Thanks

You need to install/enable the OEL public yum server http://public-yum.oracle.com/ to the guest.
The guest additions have no barring on the network however so you will need to fix that first.
