As originally installed, there is a soft link to a non existent path for build: /lib/modules/2.6.18-274.el5/build in CentOS 5.7 running under VirtualBox. This creates a problem when you try to run the VBoxLinuxAdditions.run script, because the Make fails when the kernel directory is setup in: /usr/src/vboxguest-4.1.8/vboxguest/Makefile.include.header as: KERN_DIR := /lib/modules/$(shell uname -r)/build The soft link should actually be setup as: /lib/modules/2.6.18-274.el5/build -> /usr/src/kernels/2.6.18-274.17.1.el5-i686 After the link is fixed, VBoxLinuxAdditions.run runs without any problems.
