[SOLVED]"kernel headers cannot be found" during driver installation

Hi,
I installed arch just one or two weeks ago.
I'm now trying to install the broadcom-wl-dkms package to get my ASUS PCE-AC68 running. So I executed

# pacman -S dkms
# sudo git clone https://aur.archlinux.org/broadcom-wl-dkms.git
$ cd broadcom-wl-dkms
$ makepkg
# pacman -U broadcom-wl-dkms-6.30.223.271-4-x86_64.pkg.tar.xz

So far so good but now I get the following error:

[0] stone@STONE broadcom-wl-dkms $>sudo pacman -U broadcom-wl-dkms-6.30.223.271-4-x86_64.pkg.tar.xz

Any suggestions?



EDIT:

I found this linux-headers 4.3.3-3 File List and I decided to compare it to my /usr/lib/modules/4.3.3-3-ARCH/ so I executed:

[0] stone@STONE broadcom-wl-dkms $>ls /usr/lib/modules/4.3.3-3-ARCH/build/       
vmlinux

This clearly isn't the content on the list but I'm not experienced enough to decide whether this is the problems cause or not and how to fix it.

The lack of "[installed]" by the optional dependancies indicates they are not installed
The following plus matching output should confirm it

$pacman -Qi linux-headers 
error: package 'linux-headers' was not found

Thanks for your reply!

I thought linux-headers to be some pre-installed "linux kernel stuff" and haven't realised it's a package. *facepalm*

It's working just fine now...
