Fedora :: Error While Installing Wireless Driver Using Make In FC12

The relevant details of my setup are:
Samsung R522 laptop
Realtek RTL8192E wireless network controller (PCI)
Fedora 12, kernel 2.6.32.9-70.fc12.i686 (automatically updated using software update)

My problem is that my wireless card has never worked - basically there aren't any widely available linux drivers, and there are many threads on getting the RTL8192E to work on many different forums, e.g. here, but none specifically for Fedora, so I think that this thread could potentially guide many more users. FYI, my hardwired network connection works perfectly.

Fantastically however, by emailing Realtek support, they'll send you their Linux driver, which most people have claimed works perfectly (although why they haven't just put it on their website is beyond me). SO, I've got a Linux driver for my wireless card. When Realtek emailed me to send me the driver, they said to just 'cd' into the driver directory, then do

su
make clean
make
make install
reboot
./wlan0up or ./wlan1up

OK, so I tried to do this and get the following error:
make: *** /lib/modules/2.6.32.9-70.fc12.i686/build: No such file or directory. Stop.
make: *** [all] Error 2

I don't know enough about linux to understand this error. I really don't want to have to recompile my kernel, and I hope there is some way to install this driver with not too much hassle. How to overcome this error, and install my wireless driver so I can get wireless network access on my Fedora 12 operating system. I've found Fedora 12 really easy to use so far, but this is proving quite hard!

This is the output of 'ls -lh' in the folder which seems to be causing the error, namely /lib/modules/2.6.32.9-70.fc12.i686/
