I have Ubuntu 12.04.2 LTS installed on a VMware machine on Windows 7 host. I seem to have a problem with Kernel headers when trying to install them

I did:

sudo apt-get install gcc make build-essential linux-headers-$(uname -r)
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gcc is already the newest version.
build-essential is already the newest version.
linux-headers-3.5.0-28-generic is already the newest version.
make is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 100 not upgraded.

However, when installing VMware tools I get the following error:

make[1]: Entering directory `/usr/src/linux-headers-3.5.0-28-generic'

Any help appreciated!
